Marble is easily stained. Use less water when cleaning. Regularly wipe with a cloth dampened with mild detergent, then wipe and dry with a clean soft cloth. The heavily worn marble furniture is difficult to handle, can be wiped with steel wool, and then polished with an electric sander to restore its luster. Or use a liquid scrub to clean it carefully. Use lemon juice or vinegar to clean the stains. However, it is best not to leave the lemons for more than 2 minutes. If necessary, repeat the operation, then wash and dry. For minor abrasions, special marble cleaners and conditioners are available. In addition, for antique or expensive marble furniture, should be handled by professionals.
