Want to know how to clean a dishwasher the environmentally friendly way? Let me share my tried and tested eco-tips with you, for a clean and green machine.
Did you know that dishwashers are more energy-efficient than hand washing the same amount of dishes? Yes, it’s been proven that dishwashers use less energy, water, and soap than hand washing! This is brilliant for people like me who have a serious aversion to washing dishes by hand.
However, it’s a sad news day when you hear that you can’t just bung all your dirty dishes into your dishwasher, and voila, clean dishes. No, it turns out that dishwashers do actually need cleaning from time to time to be able to ensure that your dishes always come out clean, and to prolong the life of your dishwasher. Yup, that machine that cleans your dishes does actually need cleaning semi-regularly. If you need to take a moment to come to terms with this fact, then don’t worry, I’ll be right here – a virtual shoulder to cry on if you will.
The other week I shared with you how to clean a washing machine. The good news is that cleaning a dishwasher is a much less involved job. Here’s how to do it without using any dubious or expensive chemical-based cleaners:
How To Clean A Dishwasher
You can clean a dishwasher without breaking a sweat: promise! Let me show you my environmentally friendly cleaning technique that I swear by:
How To Clean A Dishwasher Filter
For a sparkling clean dishwasher, first you need to clean the filter.
Firstly, when the dishwasher is empty, remove the bottom rack.
Next, remove the dishwasher filter. To do this, turn it until it comes free, and then you should be able to lift it right out. Once you’ve removed the whole filter, separate it into its two constituent parts. Also, remove the metal drain cover. It should just lift off easily.
Next, pop these in a sink that’s been filled with hot soapy water, and give these a good scrub with a scrubbing brush. Once clean pop the filter back together, and place it back in your machine as you found them. Pop the drain cover back on. Now give yourself a serious pat on the back, because this is the hardest it gets when it comes to cleaning your dishwasher.
Give It A Wipe
Next, I like to wipe my whole dishwasher down with a homemade cleaning spray, such as this citric acid spray. With a gentle cloth, I wipe the door, the sides and the seals to remove any food residue, or build up.
I’ll also wipe the water spray arms of the dishwasher and inspect the spray holes on it for blockages. If there are any blockages, a quick scrub with a scrubbing brush or old toothbrush relegated to cleaning duties normally sorts this right out.
Bring On The Vinegar
Now it’s time to bust out one of my favourite natural cleaning products: white vinegar!
Don’t worry though, this is not a labour-intensive job. For this next stage of cleaning your dishwasher, you’ll be delighted to hear that it’s simply a case of running your dishwasher.
Take one small dishwasher-proof bowl, and fill this with white vinegar. Place the bowl in the middle of the top rack of your dishwasher. Then select the hottest cycle your dishwasher allows, and run this cycle with only the bowl of vinegar in the dishwasher.
This hot vinegar wash will clean out the interior and the pipework of your dishwasher and will help to remove limescale, soap scum, mould, accumulated fats, and oils from the drain hose.
My favourite thing to do at this stage is to sit in the kitchen with a cup of tea in hand, listening to the hum of the dishwasher, smug in the knowledge that I’m cleaning without actually having to lift a finger. However, it’s your call to do what you want with this time!
Once the cycle is finished, you’re done! The dishwasher is shiny and clean: no sweat involved!
How Often Should You Clean Your Dishwasher?
You should clean your dishwasher filter once a week. However, a deep clean need only be carried once every six months or so. That being said, if you do notice a smell coming from your dishwasher, or your dishes not coming out particularly clean in the interim, then it certainly won’t do any harm to do another deep clean.
Got questions about vinegar? The good news is you’ve come to the right place, as I’ve got the answers! Here is everything you could ever need to know about white vinegar for cleaning!
White vinegar is a powerhouse of an ingredient when it comes to natural cleaning and the backbone of many green cleaning recipes. However, since I published Fresh Clean Home I get a lot of questions about vinegar. From the emails and messages I receive, I can tell that people wonder just how eco-friendly vinegar is compared to other natural cleaning solutions, such as shop-bought products. There also seems to be confusion around how to use vinegar effectively in the home, resulting in some of you being disappointed with the results of your homemade cleaning products.
What I want to do in this post is answer all of your queries on white vinegar, and troubleshoot common problems. In fact, consider this post as a FAQ to all your white vinegar cleaning questions!
Let’s crack on with the questions!
How Is White Vinegar Made?
Vinegar is typically made through a two-step process of fermentation from a carbohydrate to an alcohol. From this alcohol, it’s then fermented into acetic acid. In other words, sugar is converted into alcohol, to which water is added and then fermented into vinegar. The carbohydrate in question in the case of white vinegar can be corn, rice, or sugar.
In short, vinegar is comprised of water acetic acid, and trace amounts of vitamins and minerals. There are no other hidden nasties.
Is White Vinegar Eco-Friendly?
When you look at how white vinegar is made, and what it is made from, white vinegar itself is considered eco-friendly, particularly when it comes to natural cleaning. It’s 100% all-natural, biodegradable, vegan, hypoallergenic, and non-toxic. All of the good stuff, really.
Is Vinegar Made From Petrochemicals?
I have heard reports of some white vinegar brands possibly being made with petrochemicals. However, I found nothing authoritative or conclusive on the subject. I then read this informative article in The Washington Post. The conclusion I came to from this was that this potential misinformation may have been the result of some dubious marketing from Heinz in the States. Advertising activity that would possibly have been thrown out here in the UK by the Advertising Standards Agency.
Heinz’s advertising activity around their vinegar would be like a toothpaste brand stating in their advertisements that they are microbead free, when in fact microbeads in toothpaste were banned three years ago. Inferring that others do use petrochemicals, when actually they don’t, certainly sows a seed of doubt and misinformation, and I can see where this doubt has come from. However, I will keep an open mind. If I find out otherwise I will certainly update here.
What Is Vinegar’s Carbon Footprint?
Where I think that vinegar falls down as a truly green cleaning solution, is that like anything, white vinegar has a carbon footprint. White vinegar is mostly made of water, so there is a carbon cost of transporting a heavy product that has a high water content.
However, I think this is no different from buying conventional cleaning products, which are also mostly water-based. Homemade cleaning products also contain fewer harsh chemicals compared to shop-bought alternatives. And if you buy vinegar in bulk there is a huge reduction in plastic usage compared to buying shop-bought cleaners.
Meanwhile, using vinegar to make natural cleaning products can be much cheaper. This makes it a more accessible natural cleaning option for many. I will leave this one up to you to decide whether white vinegar as a cleaning solution matches your own environmental ethics.
Is Vinegar Safe For the Environment?
As vinegar is edible and easily biodegrades, vinegar is considered an eco-friendly natural cleaning ingredient. And unlike bleach-based cleaners, vinegar is also considered safe for use in septic tanks. This is because vinegar won’t harm the good bacteria in your septic tank.
What Can You Clean With White Vinegar?
So many things! The acidic nature of white vinegar means you can take on dirt, grease, and grime with ease in the kitchen, bathroom, and general living areas of your home, as well as in your garden.
One of my favourite things I’m making at the moment is my homemade cleaning wipes solution. I use these wipes to keep on top of cleanliness in my bathroom in between big cleans.
White vinegar also acts as a natural disinfectant and can kill common germs like salmonella and E. coli. However, as white vinegar is chiefly used as a cleaning product, rather than as a disinfectant, then in these Covid times, or when using to clean surfaces where raw meat has been prepared, white vinegar is best used in tandem with something antibacterial to guarantee all germs are killed. I like using these plastic-free refill anti-bacterial sachets* for no-fuss zero-waste germ killing.
If you would rather use an antibacterial cleaner on your hard surfaces just now, then it doesn’t rule out the use of vinegar around the home. I use vinegar in my laundry to soften my clothes, and to clean my washing machine. It will even tackle laundry stains. Meanwhile, white vinegar is also amazing at tackling mineral deposits on glass – such as shower screens.
I would rephrase the question, and instead, you should be asking, what can I not clean vinegar with. This leads us nicely on to the next section…
Where Should You Not Use Vinegar?
White vinegar is a great natural cleaner for many cleaning applications. However, it’s important to remember that vinegar is an acid. This means there are a few things you should not clean with vinegar.
White vinegar isn’t suitable to clean natural stone, or granite, marble, quartz, or similar. This is because vinegar can be corrosive to these materials, and may etch the surface.
Metallic paint is another no-no – so avoid using vinegar-based cleaners to clean your car. Back in the 1980s, before strict pollution controls were in place, acid rain was a huge environmental problem. And at the time, one unlikely problem that acid rain threw up was damage to paintwork on cars. This was particularly a problem for dark coloured cars and those with a metallic finish. Thankfully, acid rain is one environmental problem we don’t have to worry so much about anymore. However, it’s a great lesson on keeping acid away from your car.
What Should You Not Mix Vinegar With?
As powerful as vinegar is, it can be a little bit anti-social, shall we say. It simply doesn’t mix well with others. I’m sure we’ve all come across someone like that in life!
In some cases, mixing vinegar with other products can be damaging to your health. In other cases, mixing vinegar isn’t dangerous, but will create an ineffective cleaning solution. The chances are, if you have made a homemade cleaning product before and mixed vinegar, for example, with bicarbonate of soda, then you will have been disappointed with the results.
Here’s the full list of what you shouldn’t mix white vinegar with when you are cleaning or making cleaning products:
Mixing vinegar with bleach, or other cleaning products that contain bleach releases toxic chlorine gas. This resultant gas can be harmful to your health. Chlorine gas exposure, even at low levels and short periods of time, will irritate the eyes, throat, and nose. It can also cause coughing and breathing problems. More severe exposure can cause chest pain, severe breathing difficulties, pneumonia, and fluid in the lungs, and potentially lead to death. In short, keep your bleach well away from vinegar or any homemade cleaning products that contain vinegar.
Hydrogen peroxide is a great more environmentally friendly disinfectant that I often use around my home. However, mixing vinegar with hydrogen peroxide releases peracetic acid. This is a corrosive acid that can severely harm your eyes, nose, throat, skin, and lungs. Avoid mixing the two together at all costs.
Liquid Castile Soap
Liquid castile soap is a great all-natural soap that can make a whole host of natural cleaning products. I use it in so many of my homemade natural cleaning products, like this DIY cleaning spray. However, I keep this soap well out of cleaning products I make that contain vinegar. This is because white vinegar causes the component parts of liquid castile soap to separate, leaving you with an oily mess that won’t be good for cleaning anything. If you do want to add soap to vinegar-based products, use dish soap, which doesn’t separate when mixed.
Bicarbonate of Soda
Vinegar is an acid, and bicarbonate of soda is a base. If you can remember your secondary school science lessons, you might recall that when an acid and a base are combined, they react and neutralise each other. This means when vinegar and bicarbonate of soda react you are left with a weak salty water solution that isn’t great for cleaning with.
Again, borax is a great natural cleaning staple. However, like its cousins, bicarbonate of soda and soda crystals, it is a base and would be neutralised by vinegar, so just don’t do it!
How Do I Make A Cleaning Solution With Vinegar?
To make a homemade cleaning solution with vinegar, simply pour 250 ml white vinegar into a jug, and mix with 250 ml cooled boiled water. It’s important to use cooled boiled water because this helps to kill any germs or bacteria that may shorten the shelf-life of your cleaning solution. Next, decant the solution into a 500 ml spray bottle, and spray and wipe. For an added kick, you can also add a tablespoon of washing-up liquid, and/or 20 – 25 drops of essential oil. This will have a shelf life of up to 8 weeks.
Now you know the basic vinegar cleaning solution, I’ve got lots of other vinegar-based natural cleaning products that you can make, including:
Can You Use Other Types of Vinegar for Cleaning With?
I personally don’t recommend using other types of vinegar for cleaning with – only white vinegar. Malt vinegar, compared to white vinegar, for example, has a much stronger smell. What’s more, there is the potential that malt vinegar’s dark hue may cause staining on light coloured surfaces. Other dark coloured types of vinegar may also have the potential to stain. Meanwhile, other types of vinegar, such as white wine vinegar or apple cider vinegar, aren’t cost-effective to use in larger quantities. I buy my white vinegar in bulk for cleaning, for a little as £7 for 20 litres, making it a really economical choice.
What If I Don’t Like The Smell of Vinegar?
Not everyone likes the smell of vinegar. I understand. The good news is that it’s quite rare to use neat white vinegar in cleaning solutions. It’s mostly used diluted – in a ratio of 50/50 white vinegar to the water, so you’re not getting a full blast of vinegar. Even at that, not everyone is a fan. If you or someone in your household is sensitive to the smell of vinegar, then you can infuse fruit peelings and herbs in vinegar. This creates a fresher scent that’s easy on your pocket.
Alternatively, you can scent your vinegar-based cleaning products with essential oils. I find that 20 to 25 drops of essential oil to 250 ml of cooled boiled water and 250 ml of white vinegar is the sweet spot between scent and cost-effectiveness, but feel free to add more or less depending on your nasal preferences. I’m putting together a post on the best essential oils for natural cleaning, so do watch this space.
I’ve been using white vinegar to clean with since 2008, and what I have found is that I now equate the smell of vinegar with cleanliness. Especially if you are used to cleaning everything with bleach, it will take time for your brain to adjust from the smell of bleach equals clean, to the smell of vinegar equals clean. Give it some time, and if it’s not working for you, then there’s no shame in trying something different. This citric acid cleaning spray, for example, is vinegar-free, but still has many of the benefits of cleaning with vinegar without the smell.
I hope this post helps you with all of your vinegar-based questions. If you have any more, leave them in the comments below, or drop me a message and I will endeavour to answer them here.
