Most DIY cleaners are made from a type of vinegar or alcohol, both of which are powerful disinfectants and cleansers. Inexpensive, clear-grain alcohol (such as vodka) is a gentler disinfectant. It can clean and disinfect but won’t kill viruses. Isopropyl alcohol is quite strong and typically used in medical and industrial applications, but it is safe in the home in small amounts. Vinegar is my natural bleach alternative. The acetic acid is best used diluted, such as this cleaning spray recipe above, and works hard to eliminate scum and stains.
