No matter how well you maintain your home, even a tiny bit of dampness is enough to cause a ceiling watermark…
Before you haul out the ladder, drop sheet and rollers to repaint, try this little trick. It could save you a lot of money and time!
All you need is a 10% bleach solution in a spray bottle. If the stain is old, however, you may want to go directly to a commercial mildew and mould remover. Spray the spot thoroughly, and allow it to dry for a day or two.
While it won’t fix actively damp stains, it’s enough to clear out almost every dried watermark on your ceiling.
It doesn’t mean that there was mould on the stain, either, but these solutions also offer a very light bleaching action that should be enough to disguise the discolouration that the water left behind.
Do be sure to wear glasses or goggles when you spray, and be sure not to let the solution get onto carpets or walls.
