How to Clean Greasy Kitchen Cabinets?
A layer of grease on kitchen cabinets can fight traditional cleaning methods. Spray cabinets with vinegar to remove light grease. Reduce grease moderately with oily or greasy dishwashing detergents or laundry detergents. Treat and remove stubborn oils with a paste made from baking soda and vegetable oil.
Clean dirty kitchen cabinets.
Prepare the vinegar solution. Pour uncooked white vinegar into a spray bottle. If your cabinets are fragile, make a mild vinegar cleaning solution by mixing equal parts vinegar and warm water in a spray bottle. 
If you don’t have a spray bottle at home, you can buy one at most supermarkets, hardware stores, and department stores.
Vinegar is especially good at removing the sticky film that sometimes gets left on your hands. Use vinegar if you have small children leaving greasy handprints on the cupboards.
Test the solution on a small area of the cabinet.
Spray the vinegar solution on a small area of the closet and let it work. After about 5-10 minutes, wipe the case with a cloth and check for a change in color. If not, you can continue cleaning with a vinegar solution. 
If the shell looks discolored, your solution may be too strong. Mix another solution with more water and less vinegar and try again.
Clean stained cabinets with vinegar.
Be especially careful when fogging. Apply a thin layer of vinegar solution to all cabinet surfaces. Leave the solution for 5-10 minutes after application.
Do not overload the cabinet with the solution. Doing so can damage wood, peel paint, or rust metal. 
Wet the cabinets again and clean them.
After the vinegar has had time to set, clean the cabinets again as before. Then use a clean, soft towel to wipe off any accumulated grease and grime.
Use a soft brush on stubborn areas.
Heavily soiled cabinets may require light polishing with a non-abrasive sponge. Gently wipe the scrubber in circular motions on stubborn oily areas.
Using abrasive cleaners can damage the finish or finish of your cabinets. Before using the scrubber, test it in an inconspicuous area of the cabinet.
Dry cleaning of cabinets.
Dry your closet with a clean, soft, lint-free cloth. When the cabinet dries, you can see or feel the remaining grease. Repeat this process as needed until your cabinets are degreased.
Prepare a soap solution.
Fill a bucket with warm water and add a little oil or non-greasy soap. If you plan to use laundry detergent, in most cases you should add 1 cup (237 ml) of detergent for every 2 cups (473 ml) of water. Stir the solution to disperse the soap in the water.
Some soaps or cleansers may be in concentrated form. In these cases, it may be necessary to reduce usage. Follow the directions on the cleaner’s label for best results.
Apply dish soap with a rag.
Dampen a soft, lint-free cloth with soapy water. Drain excess solution into a bucket. Wipe all surfaces of the cabinets with a damp cloth and apply a thin layer of the solution to the cabinets. For heavy fats, let the solution sit for about five minutes.
Clean grease from cabinets.
Dampen the cloth again with soapy water and wring out the excess. Wipe the cabinet thoroughly with a cloth to remove grease and other deposits. If your fabric gets dirty, soak it in water, wring it out again, and wash it.
Some cleaning may be required to remove stubborn grease. Use only non-abrasive cleaners. Be sure to test the cleaner on an inconspicuous area of the cabinet before cleaning exposed areas.
