If the surface already has lingering water, such as from a shower, you don’t need to add more.
Choose a water-based cleaner with a neutral pH. It’s the safest option for cleaning your cultured marble without damaging the glaze or scratching the surface.
Use a soft cloth to avoid scratching or damaging the surface. Don’t use abrasive sponges or cloths. If your cloth is very wet, switch to a clean, dry cloth to remove the remaining cleanser.
Stick to mild soaps and cleaners.
Too much white vinegar can cause this liquid to spread to areas of the marble that are already clean. Although this can be wiped away easily, wringing out your rag after wetting it can prevent extra work. Vinegar is a great option for removing hard water stains or built up soap scum.
With especially light buildup or stains, you may be able to wipe these away in one swipe with your vinegar dampened rag.
Hot water in some cases can cause stains to stick to surfaces more stubbornly. Using cold water will prevent this from happening. [9] X Research source
Although proper usage will vary from product to product, in many cases you can combine a product, like Barkeeper’s Friend, with a small amount of water to make a paste. Apply this to remaining stains or buildup for a few hours. Generally, by allowing your cleaning product more time to work on the stain, the results will be better. However, this may not be the case with all cleaners. Be sure to check the label. [10] X Research source
Polish the marble with a suitable polishing agent, such as countertop wax, and a soft rag or polishing cloth to restore its luster. [11] X Research source
Avoid using this technique if your marble is dark colored. Hydrogen peroxide on dark colors can lead to lightening. [13] X Research source Less serious stains may only need 15 minutes to a half hour of time before the stain can be wiped away. Check less serious stains at regular intervals for this reason. If, at a glance, you can tell the stain you are working on will require heavy-duty techniques, you may want to skip the peroxide treatment and move straight to mixing a heavy-duty cleaning solution.
Heavy-duty stains may remain after cleaning the surface with peroxide, in which case you’ll need to mix a heavy-duty cleaning solution. [14] X Research source
As an alternative to heavy-duty cleaners, you can use paint-thinner or denatured alcohol to remove the stain. However, always test these cleaners in an inconspicuous place on your cultured marble first, as they may damage the surface. Although this cleaning solution is made with household products, it can be harsh on your skin. Wear gloves when using this solution to prevent dry skin and irritation.
Some stubborn stains might require a longer soak time. However, soaking your marble too long in this solution may be harmful to its finish. [16] X Research source
The surfaces cleaners are intended for should be clearly marked on the label. Abrasives, too, are generally marked on the label. [18] X Research source
Only use this technique for marble that is light in color. Bleach may cause discoloration in dark colored pieces. [20] X Research source
