Hello Shana33,
Welcome to the forum. Grease can be a big problem. Try one of our suggestions below to get your kitchen walls looking clean and spotless again:
First you might want to try a product called TSP; you can buy this from your local hardware store, TSP is a heavy duty cleaner that neutralizes and floats away grease, grime, dirt, oil and smoke film. You can use this on walls, floors, woodwork, outdoor furniture, and more. It contains no phosphates, soap, lye or abrasives. Use a dust mask and gloves and have good ventilation when using this product; follow the package instructions.
If you don’t want to try the TSP here are some other suggestions:
Vinegar can be helpful in cutting grease. Let the vinegar sit for a few moment then wipe off with a damp sponge.
Baking soda is alkaline and is helpful on stains. It is good for scrubbing stains and is non-abrasive on most surfaces. Generously sprinkle the soda on a cloth with warm water and then rub it into the greasy area. Let this moist mixture sit on the area for a few moments then wipe off with warm water.
Liquid dishwasher soap also works for some stains, but keep in mind that it usually contains bleach. Again, apply to the stained area, rub, and rinse.
Degreasers are also good. You can try professional strength 409 or a similar spray degreaser, just spray and wipe.
You could also try Spic and Span Powder. It contains soda ash, which is a good cleanser and is used in many types of detergents. It is generally effective at cutting grease stains.
You may also want to consider using a splatter screen to help keep the grease down to a minimum.
Be sure to wear gloves and always rinse the cleanser residue well.
As always, test an inconspicuous area first.
Good luck,
Mrs. Clean
