Diluted white vinegar can help with light mineral scale, glass, and some washable surfaces, but its acidity is not suitable for every material. A practical rule is to use it only where mild acids are allowed and never mix it with bleach.
It can work well on some mineral deposits
Compatible faucets, glass, and parts with light mineral scale may respond well to a diluted solution and short contact time. Rinse afterward so acid does not sit on seals, coatings, or metal longer than necessary.
It can be useful on glass and some washable surfaces
On glass without special coatings, a mild solution can help remove mineral film. For countertops, flooring, and appliances, check care instructions first because the protective finish may be more sensitive than the underlying material.
Avoid calcareous stone and acid-sensitive finishes
Marble, travertine, and other calcium-based stone can be etched by acid. Some sealers, rubber components, and appliance coatings also should not be repeatedly exposed to vinegar.
Never mix vinegar with bleach
Acid mixed with hypochlorite bleach can release dangerous chlorine gas. Use one product at a time, rinse when appropriate, and always follow the label on commercial cleaners.
