Clean Organized Family Home suggests vacuuming mini blinds with a hose attachment. Then, the blinds can be wiped down with a damp rag and mild dish soap.
Use a vacuum brush to help loosen and suck up surface dirt. Vacuum the front and back of the blinds. After vacuuming, moisten a damp rag with mild dish soap and wipe down each blind slat. The dish soap cleans the blinds and helps prevent dust from sticking to the slats. Gently wipe the blinds dry with a clean cloth. Clean wood mini blinds using a soft rag and lemon oil instead of a damp cloth.
