How Do We Calculate This?

How We Test - In the Lab

Fill an 8 oz spray bottle with water, then add one teaspoon of liquid soap. Mix thoroughly. Mix 1/2 cup baking soda ¼ cup of salt in a small shaker container. Mix an additional ¾ cup of baking soda and ¼ cup salt in a plastic bowl with ¼ cup of water. Mix to make a thick paste. Next cover any holes in the bottom of the oven with foil to prevent the cleaning mixture from leaking onto the broiler. Spray the oven with the soap and water mixture. Then sprinkle the dry baking soda and salt mixture over the soap mixture. For the oven walls spread the salt and baking soda paste over the walls with a sponge. Leave the mixture on for several hours (overnight is even better). Spray with the soap and water mixture, and wipe with rags. A rinse of a mixture of half white distilled vinegar and half water is a good way to dissolve any soap residue.

How We Test - In the Field

TURI staff, cleaning professionals and/or residential cleaners field test products based on criteria co-developed by TURI and typical users to enable realistic performance evaluations in actual environments. End-user impressions, level of difficulty, productivity and other factors are documented. Video of product tests assists the evaluations whenever possible.

The Dirt

The natural buildup of an oven, which includes the residue of various greases, food residue, and burned stains.
