A Guide to Cleaning Household Surfaces
Use: Plain water.
Tools: A microfiber cloth.
Tips: For extremely dirty mirrors, make a solution of one part vinegar to one part warm water and use a squeegee. Keep water or the vinegar solution away from the edge of a mirror; moisture can seep behind the glass and cause damage.
Tough stains: Rub tough streaks with crumpled newspaper and the vinegar solution.
