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.
What not to do
Melamine foam should be avoided for Painted walls
Best avoided
The available guidance advises against this.
It removes the mark and burnishes the patch, so the clean spot then reads as a new mark.
Precautions
- Test on an inconspicuous area first

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, no claim is made.
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, and every condition comes from the same document.
Precautions
- Test on an inconspicuous area first
- Limit the contact time

Soap is safe on, in specific conditions, Painted walls
Safe only in specific conditions
This is only appropriate within specific limits. Outside those limits, no claim is made.
Only within these limits:
- WAIT AT LEAST TWO WEEKS AFTER PAINTING before using any water or cleaner on the wall
- Dust first with a vacuum dust brush and then a tack cloth, whatever the paint type or sheen
- Mild soapy water on a soft cloth or sponge, thoroughly wrung out, gentle pressure in a circular motion
- Rinse with a clean damp cloth to remove leftover cleaner
Too much water can ruin the paint finish, which is why the wringing instruction is explicit. The manufacturer also gives the pass condition for the test patch: the paint still looks bright and no water marks remain after drying.
Precautions
- Test on an inconspicuous area first
- Rinse thoroughly afterwards

Detergent is safe on, in specific conditions, Painted walls
Safe only in specific conditions
This is only appropriate within specific limits. Outside those limits, no claim is made.
Only within these limits:
- A grease-cutting dishwashing soap in WARM water, for grease splatters such as those on kitchen walls
- Test the solution and the technique on an inconspicuous spot first
- Cloth thoroughly wrung out; rinse afterwards with a clean damp cloth
The manufacturer distinguishes the general wash from the grease case and gives a different product for each, which is the distinction most wall-cleaning advice loses.
Precautions
- Test on an inconspicuous area first
- Rinse thoroughly afterwards
