Gather your pine branches. Then give them a shake to remove any bugs and beasties that might be residing in the branches.
Next, pop the pine branches into your jar. You may need to cut them into smaller sections using scissors, if your branches are too long.
If you have any citrus peel, feel free to add these too for a extra fresh scent burst.
Next, pour in your vinegar until it reaches the top. Your branches and peel, if you added any, should be submerged.
Pop the lid on, and let the ingredients infuse for at least two weeks in a cool, dark place. The cupboard under your kitchen sink is an ideal place for this. Two weeks would be the bare minimum. For stronger pine scented vinegar, leave the pine steeping for longer. I’ve left herbs and citrus infusing for as much as six months, for stronger smelling infused vinegar.
Once you’ve finished infusing your vinegar, use a colander or sieve, and strain the mixture into a measuring jug. Place the pine branches (and citrus peel, if you used it) into your compost bin.
Next, fill your clean, dry spray bottle halfway with the pine-infused vinegar. Then top the bottle up with cooled boiled water, so that is it a 50:50 vinegar/water mix. Pop any unused vinegar back in your jar, and pop the lid on.
