Flat paint can be a real pain to clean. Here are some tips on how to get it looking brand new again:

  1. Use a mild soap and water mixture to clean the surface. Make sure to rinse off all the soap residue.
  2. If the paint is particularly dirty, you may need to use a cleaner specifically designed for flat paint. Follow the instructions on the bottle.
  3. If the paint is still dirty after using one of the above methods, try using a cloth dipped in white vinegar or lemon juice and water mixture to clean it off. Be sure to rinse off all of the vinegar or lemon juice before applying any new paint! ..
