Is cleaning grout or tile on the to-do list for your facility? Ever notice a white haze left on the floor after they’ve dried? This frustrating issue is called efflorescence, and it appears as a white powder on the grout. It’s particularly noticeable on dark-colored grout, and it can make your job look less than well-done.
How can I prevent efflorescence?
This issue can happen any time moisture contacts masonry material, including ceramic flooring, concrete or grout. You can reduce the risk of it forming by drying your floors as quickly as possible after cleaning using an armorer, sealing grout lines once the floors are dry and choosing a sealer with a solvent carrier. These steps will keep moisture away from your grout.
How can I deal with efflorescence if it develops?
Don’t despair! There are a few ways to deal with efflorescence once it appears on your grout. Some may be removed simply by foot traffic over time, but if you need a quicker, more serious fix, reach for a stiff brush.
If brushing doesn’t remove the salty, hazy deposit, choose a concentrated acidic grout cleaner (ask us for recommendations!). Apply the solution using a damp mop or sponge, but remember that using too much water will only make efflorescence worse. Wear gloves and splash goggles to keep yourself safe and use the smallest amount of water possible to remove the acid. Dry the floor well using an air mover to prevent efflorescence from returning.
