HOW TO CLEAN GREASE OFF WALLS
Every time you cook, grease and oil splatter up from your pots and pans and onto the surrounding kitchen walls. Over time, this cooking grease builds up, leaving a residue and attracting dust and dirt onto those spots.
Removing grease stains as soon as they make their way onto your walls is ideal. The longer those splatters and stains sit, the harder it will be to remove them later.
If you're looking to get grease stains off walls, you should avoid using bleach, which can ruin paint and stain other surfaces. Baking soda isn't very effective on grease and it can scratch dull paint, while white vinegar shouldn't be used on unsealed stone, grout, or other porous surfaces.
Because TSP (Trisodium Phosphate) is corrosive, you'll usually need to repaint if you use it to clean a painted wall. Ammonia is another popular option for cleaning and degreasing walls, but breathing in its fumes can lead to irritation of the eyes, nose, skin, throat and respiratory tract. Even low concentrations of ammonia fumes can aggravate the respiratory condition of people with asthma. Both TSP and ammonia would also require you to protect yourself with rubber gloves and goggles when cleaning grease off kitchen walls.
It's important to use a non-abrasive cleaning solution that will get grease off walls without discoloring or diminishing the paint or finish. Whether your walls are painted with latex, oil-based paint, tiled, or covered in wallpaper, using Simple Green All-Purpose Cleaner on a regular cleaning schedule can keep dirt and stubborn grease stains off them.
