Marble is very porous and if dirt is deeply embedded, it may need to be sandblasted, says an environmental Residential Cleaning Service in Evanston, Il. If your once stunning marble has dulled from dirt and grime, here are two cleaning options to try before resorting to sandblasting as noted in the book "Natural Cleaning for Your Home" by Casey Kellar.
Light Dirt Marble Cleaner: Peroxide: Water
Mix the peroxide and water in a spray bottle. Spray onto the marble, then rinse. Shelf life is approximately 6 months.
Heavy Grime Marble Cleaner: 3/4 cup borax: 1/4 cup water
Mix the ingredients into a paste and use a sponge to scrub. Discard any remaining paste.
Stainless Steel is a popular kitchen metal because its hard surface is not porous, making it thoroughly clean. The following formulas can be used to keep it thoroughly clean.
Baked on Dirt Remover: Stainless Steel Polish: Borax: Water
Let the Stainless Steel Polish sit on the item for about 1 hour. Rinse well, then follow with a 50-50 mix of borax and water. Scrub with an abrasive sponge and plenty of elbow grease. Rinse well. No shelf life.
Stainless Steel Polish
1/2 cup ammonia: 1/2 cup water
Mix the ingredients in a spray bottle. Spray on and rinse off. Shelf life is approximately 6 months.
Bronze is a hard metal that does not respond well to abrasives, but it can be cleaned effectively with oils.
Bronze Cleaner and Polish: 1/4 cup linseed oil: 2 tablespoons safflower oil: 2 drops orange essential oil.
Mix the oils together and store in a bottle. Shelf life if approximately 6 months.
With these natural cleaning and polishing formulas, your Marble, Stainless Steel, and Bronze should last and shine for years to come, says an environmental Residential Cleaning Service in Evanston, IL.
