How can I remove a water stain from the ceiling?

I'm unaware of anything that will remove it but Kilz spray paint will cover and for some reason normally is a color match.

Kilz covers water stains. Then repaint with your ceiling paint.

Check your roof for leakage.

Once you've figured out the source of the stain and repair it, then paint over the spot.

Use killz primer to paint over the stain

We used Kilz paint and that was successful.

Wipe the stain using a mixture made of one part bleach and three parts warm water, or use a cleaner that has already been premixed. Next, use a moist rag to remove the solution, and use a towel to dry the area. Allow the ceiling to dry completely by waiting a few hours.

Use Stain Blocker from DIY store and then over paint.

You can use watered down bleach lightly dabbed on the stain as not to soak it. It should magically clear up. Otherwise use a stain blocking primer and repaint.

Hi Rosario, hope this helps you. Use 1 part bleach to 3 parts water. If you don't want to use bleach but do want something other than water, try vinegar, borax or branded products that you can find at a hardware store or home center, which also kill mold.
