How to clean exterior wall that has old paint and moss?
Tried pressure washing,
the old paint is falling off, and some of the moss just can't come off without the paint falling off.
Any detergent that can be used?
Have tried bleach but it stains the wall! Also don't have enough money for an exterior paint this year, so would like to clean instead.
Thanks!

Usually, bleach can work well if you scrub your exterior wall, 15 minutes after you sprayed it on the surface with moss. But if bleach didn't work, you may try adding ½ cup of ammonia to a bucket of water and rinse well.

Fill a sprayer (Home Depot or Lowes have them) half way with bleach, half way with warm water. Spray the surface of the home. Pressure wash. Then spray again, and scrub any moss or mold left. Bingo. Clean exterior.

Scrape off the moss then pressure wash it with TSP. Then scrape the loose paint off. If there is moss growing on it it may be rotten.
