1. Check the paint type and sheen
This is so you know just how hard and long you can scrub before possibly damaging the paint.
2. Grab 2 small buckets, towels, a duster, a sponge, a quarter cup of dish soap, warm water, and a non-ammoniated cleaner for tougher spots
These are all the tools and materials you should need to clean even the toughest of stains.
3. Clear the area in front of where you’re cleaning
This makes getting to the area that needs cleaning much easier. It also helps keep those things from getting splashed.
4. Lightly dust the area
This helps the water and cleaning solution do a better job.
5. Line the area below with towels
This protects the floor or carpet from getting wet.
6. Fill one pail with warm water
You can start trying to clean the painted wall with just warm water and a sponge first. The sponge should be damp, not soaking wet.
7. Fill the other pail with warm water and a quarter cup of dish soap
If the warm water doesn’t work, it’s time to kick it up a level. Dish soap can take care of a lot of impurities without damaging the paint.
8. Lightly scrub your walls with the soapy water from the bottom up
Going from the bottom up helps prevent streaking. The water doesn’t drip as much this way, which can cause streaking. If the water does drip, it’s onto damp areas and not dry ones.
9. Gently wash with a damp rag dipped in warm water
Use the rag and warm water to clean the dish soap off of your painted walls. You don’t want the dish soap leaving a residue behind.
10. Lightly dry
Dab the wet spots with a dry rag until your walls are dry.
11. Use the non-ammoniated cleaner if necessary
If the dish soap doesn’t work, then it’s time to go to the last level for the best way to clean painted walls. The non-ammoniated cleaner should get rid of most blemishes. Use it, then wash the area with a damp rag, then lightly dry.
