Vinegar is a natural, eco-friendly cleaning agent. It is also inexpensive and non-toxic. Vinegar can be used for many things, like cleaning windows, removing stains from clothes or floors, and of course, as a cleaner for paint equipment. There are many benefits to using vinegar as a cleaner for painting tools: it doesn't leave any residue or build up on the equipment; it doesn't have any harsh chemical odors; it's environmentally friendly and inexpensive. Vinegar is also safe to use on aluminum and stainless steel surfaces.
