Dust and vacuum off any loose dirt/dust. Use a water/vinegar solution and wipe the blinds with a soft cloth or a sock.
Use a microfiber cloth to dust. Then slightly dampen the cloth to clean
Hi Maria. Once a year (in the summer) I put my blinds in the tub and wash them down with water and Dawn dish soap. I put an old sock on my right hand and wash in between each slat. Once clean I take them outside to rinse with my garden hose. Then I lay a sheet in the grass and put the blinds on it to dry.
