I tried to clean spots off of my wall and now the spots are worse. Can I fix them without repainting the whole wall?
Spot prime the spots then touch them up with the original paint. If the spots are small use a spray can of primer like Zinnser Cover Stain or BIN. For the touching up use a small mini roller, touch up kits are available that will work well.
Touching up should work but it depends on the color and quality of paint originally used.
