Grease Build Up in the Kitchen

A hand held steam cleaner will do it fast. If you don't own one or don't want to buy one you can rent one I am sure.

Murpy's Oil Soap does a very good job on greasy kitchen cabinets. If they have been neglected too long, you may have to repeat the scrubbing, but you will be able to see, and even feel, the difference.

Try a product called Grease Lightning. It's amazing.
