Quick answer

Match the cleaner to the surface: vinegar may help glass and some fixtures, but it can damage stone, unsealed grout, and some finishes. Test first, use dwell time instead of force, and stop if deposits return from a leak or water-quality issue.

Do not mix cleaning chemicals. Do not open electrical panels, gas lines, sealed appliance systems, structural assemblies, or hidden plumbing. Stop if you smell gas, see sparks, find sewage, discover extensive mold, or feel unsure.
