How to clean cultured marble
Dampen a clean rag with white vinegar.
Your rag should be wet through with white vinegar, but excess vinegar should not drip or seep from the rag. Either pour vinegar onto your rag in a sink or dunk your rag in vinegar in a bucket.
Wring out the rag lightly over a sink. Too much white vinegar can cause this liquid to spread to areas of the marble that are already clean.
