Vinegar the frugal and earthfriendly way to clean

Get a empty spray bottle and add equal parts vinegar to water.
This can be used to clean windows.
For all surface cleaner add a bit of liquid soap if you don't like the smell.
It can also be used to cut down detergent residue if you put some in your washer.
Get apple cider vinegar and use as a clarifying shampoo for your hair.
It smells a little better than white vinegar but your hair will smell different for a day or so but it will feel healthier.
