“What is the best way to clean blinds?”
In my opinion there are two situations for cleaning window blinds. There is the “once every couple of weeks wipe down” and then there’s the “once every 6-12 months major clean”.
For the “once every couple of weeks wipe down” I’d recommend a lambs wool duster, like this one from Amazon. It’s fast, easy and very efficient and effective.
For the “once every 6-12 month major clean” I take them completely down, take them out to the driveway, patio or someplace else where there’s a hose nearby, lay them down flat and spray them down really well with the hose. For tougher, and really dirty blinds I spray a little Greenworks All Purpose Cleaner on them, scrub them down with a sponge or cleaning brush, and then spray them down with the hose. You will have to leave them out to dry for most of the day but they’ll be sparkly clean and look new again!
