How to Clean Walls with Flat Paint?

Cleaning walls with flat paint requires a gentle approach to avoid damaging the delicate finish. Start by dusting with a soft microfiber cloth, then spot clean stains using a mild soap solution or vinegar mixture. For whole wall cleaning, work from top to bottom using circular motions with a damp cloth. Always rinse with clean water and dry immediately to prevent water stains. For stubborn marks, consider professional cleaning services.
