Vinegar only is smelly while you're actively using it and it is wet. It is the oldest, safest, best cleaner around and has been used by generations. The downside is the smell, that's about it. Reminds me of coloring Easter eggs.

Cleaning[edit]
White vinegar is often used as a household cleaning agent.[1] For most uses, dilution with water is recommended for safety and to avoid damaging the surfaces being cleaned. Because it is acidic, it can dissolve mineral deposits from glass, coffee makers, and other smooth surfaces.[46] Vinegar is known as an effective cleaner of stainless steel and glass. Malt vinegar sprinkled onto crumpled newspaper is a traditional, and still-popular, method of cleaning grease-smeared windows and mirrors in the United Kingdom.[47]Vinegar can be used for polishing copper, brass, bronze or silver. It is an excellent solvent for cleaning epoxy resin as well as the gum on sticker-type price tags. It has been reported as an effective drain cleaner.[48]
The use of vinegar in dishwashers and washing machines can cause damage to their rubber seals and hoses, leading to leaks. According to testing done by Consumer Reports, vinegar is ineffective as a rinse aid and in removing hard-water film while used in a dishwasher. According to Brian Sansoni, chief spokesperson for the American Cleaning Institute, vinegar "isn't very useful with stains that have already set into clothing, including food stains and bloodstains."[49][50] Other household items and surfaces that can be damaged by vinegar include flooring, stone countertops, knives, the screens of electronic devices, clothes iron water tanks, and rubber components of various small appliances. Common metals that can be damaged by vinegar include aluminum, copper, and lower-quality grades of stainless steel often used in small appliances.[49]
