Painted walls
A soft coating that is still curing for weeks after it looks dry, and that is damaged by water as readily as by any cleaner.
Precautions
- Test on an inconspicuous area first
- Limit the contact time
In detail
A painted wall looks finished long before it is. The paint manufacturer's first instruction is a waiting period rather than a technique: wait at least two weeks after painting before using any water or cleaner on the wall. After that, washing is a soft cloth or sponge with mild soapy water, gentle pressure in a circular motion, then a rinse with a clean damp cloth to lift the leftover cleaner. The constraint that catches people is quantity rather than chemistry — too much water can ruin the paint finish, so the cloth is wrung out thoroughly, and a wall is never really washed so much as wiped. Dusting comes first regardless of paint type or sheen, because dragging a damp cloth over dust makes a slurry and spreads it. For a scuff the guidance suggests a paste of baking soda and water, gently rubbed then rinsed and dried; for grease splatter, a grease-cutting dishwashing soap in warm water. Testing is specified with an unusually clear pass condition: try an inconspicuous spot, and if the paint still looks bright and no water marks remain once it has dried, the method is acceptable.

What works
Sodium bicarbonate is safe on, in specific conditions, Painted walls
Safe only in specific conditions
This is only appropriate within specific limits. Outside those limits, CleaningHQ makes no claim.
Only within these limits:
- Not within two weeks of painting — the manufacturer says to use no water or cleaner at all before then
- Gentle pressure only, then rinse and dry
- The cloth must be wrung out thoroughly, because too much water can ruin the paint finish
- Test an inconspicuous spot: the paint should still look bright with no water marks after drying
The manufacturer suggests the paste itself; every condition here comes from the same document rather than from CleaningHQ.
Precautions
- Test on an inconspicuous area first
- Limit the contact time
