When cooking, it is not uncommon for the cooking oil to splash onto the nearby walls causing unsightly grease spots and discolorations. These stains can be difficult to remove and all-purpose cleaners do little to budge the cooking oil. The porous surface of the wall traps the cooking oil in, protecting it from removal. If possible, wipe the oil splatters off the wall as soon as they occur. The longer the cooking oil sits on the wall, the harder removing the stains will be.
Things You'll Need
Sprinkle cornstarch on the cooking oil stain, and let it sit for several minutes. Dust the cornstarch off the wall with a paper towel. Alternatively, create a paste with three parts cornstarch and one part water, and spread the paste over the oil stain before waiting several minutes to wipe off with a damp cloth.
Examine the cooking oil stain. Continue with the remaining steps if the discoloration is still visible on the wall.
Submerge a clean sponge in white vinegar. Hold the saturated sponge over a sink, and wring out the excess vinegar.
Rub the cooking oil stain in a gentle circular motion with the vinegar-dampened sponge. Continue for several seconds. Wipe the vinegar off the wall with a damp cloth.
Repeat the entire process until you have removed all traces of the cooking oil from the wall.
