Cleaning Concrete Countertops, Tubs & Sinks
Decorative concrete tubs, sinks and counters are extremely durable and offer endless design possibilities, from stamped concrete designs to unique shapes and colors. However, they aren’t indestructible. Concrete fixtures which aren’t sealed are easily stained, and most concrete contractors recommend sealing. Whether your concrete bathroom surfaces are sealed or not, proper care in cleaning can make a big difference. They should be wiped daily and thoroughly cleaned at least once per week. Here’s how to do it.
Although there are specially-formulated cleaners for concrete household surfaces, plain old soap and water is also suitable. Gentle dish washing liquid and warm water is safe for your concrete surfaces, sealed or unsealed. Simply wipe surfaces after use. If you’re looking for convenience, you can purchase disposable pH-balanced wipes, which are specially formulated for use on concrete surfaces.
For Light Stains
Unsealed concrete is much more susceptible to stains than sealed or waxed concrete. For light stains, try a strong solution of about two tablespoons dish washing liquid to two quarts of water. Thoroughly wet a dish cloth and scrub the stain gently; repeat as needed until the stain is gone. For more stubborn stains, you may need to try slightly stronger measures.
For Stubborn Stains
Powdered laundry soap and stain removers are also safe for concrete surfaces. For more stubborn stains, first spray the area with laundry stain remover and let it sit for several minutes. Next, sprinkle powder detergent over the area, and let it also sit for several minutes. Last, use a wet cloth to scrub the area. You may need to repeat the detergent and scrubbing steps for tougher stains.
The Last Resort
You may also try using a hydrogen peroxide paste, though this should only be done when all else fails. Hydrogen peroxide has a bleaching action and this method is somewhat harsher, especially for non-porous (sealed) concrete. To make a peroxide paste, combine two tablespoons hydrogen peroxide with a cup of flour and enough water to make a paste. Spread the paste directly on the stain, and leave it for several hours. You may cover the paste with plastic wrap to keep it from drying out. When you’re ready to clean, scrub the paste off with a wet cloth.
For best results, wipe spills as soon as they happen and clean your concrete fixtures daily.
