Alkali backflow on marble countertops refers to the phenomenon that alkaline substances (such as calcium hydroxide, calcium carbonate, etc.) in marble are precipitated onto the surface of the stone due to water evaporation, forming white or yellow spots. Alkali backflow will affect the beauty of the marble countertop and may cause discoloration and damage to the stone.
My bathroom marble countertop was corroded by detergent and turned white, which troubled me for a long time. I used several detergents but couldn’t wipe it off. It still turned white after drying. Until I used a stone crystal plating agent, it really became as bright as new after use, and the marble countertop no longer looked like a white surface.
DIY steps to remove alkali from marble countertops:
Tools and material preparation:
- Clean water or stone cleaning agent
- Soft cloth or sponge
- Rubber gloves
- Crystal plating agent
Methods to remove alkali from marble countertops:
- First wipe the marble countertop clean. If there are more stains, it is recommended to use stone cleaning powder to wipe it once.
- After the countertop is dry, apply the crystal plating agent on the sea surface, and then apply it evenly and fully on the alkali-returned part of the marble countertop. The strength should be clear and not too strong. Just apply it once, and then let it stand for about three days without touching water.
