Cleaning a textured ceiling requires a light hand, according to Home Guides at SFGate. First remove dust and spider webs, and then clean any spots on the ceiling. You need goggles, a broom, bleach, water, a spray bottle and textured paint.
Protect your eyes
Debris easily falls from a textured cleaning while it is being cleaned. Wear wrap-around goggles to protect your eyes.
Dust the ceiling
Use a broom with soft bristles or the dusting brush on a vacuum cleaner to carefully dust the ceiling.
Make a spot remover
Mix 1 tablespoon of bleach into 1 gallon of water in a pail. Fill a spray bottle with the bleach mixture.
Clean any spots on the ceiling
While standing on a ladder, spray any dark spots on the ceiling with the bleach mixture. Spray the spots two to three times with the spray bottle. Don't over-saturate any spot on the ceiling. Allow the ceiling to dry overnight.
Repeat the spot cleaning as needed
For stubborn dark spots, the ceiling may need to be treated and allowed to dry overnight several times.
Apply textured paint in a spray can as needed.
For stubborn spots and bare spots, select a textured paint in a color that matches the ceiling. Apply according to the directions on the can.
