Fabric Softener Sheets
Cleaning Venetian blinds is a tedious chore, so make the results last by wiping them down with a used dryer fabric softener sheet to repel dust. Wipe them with another sheet whenever the effect wears off.
Rubbing alcohol does a terrific job of cleaning the slats of Venetian blinds. To make quick work of the job, wrap a flat tool — a spatula or maybe a 6-inch (15-centimeter) drywall knife — in cloth and secure with a rubber band. Dip in alcohol and go to work.
Forget wasting money on those expensive products for cleaning Venetian blind slats. Just slip a sock over your hand and gently rub the dust off. You can use some dusting spray on the sock, if you like.
You can make the job of cleaning mini-blinds or Venetians considerably less torturous by giving them “the white glove treatment.” Just put on a white cotton glove — the kind sold for gardening is perfect — and moisten the fingers in a solution made of equal parts white vinegar and hot tap water. Now simply slide your fingers across both sides of each slat and prepare to be amazed. Use a container of clean water to periodically wash off the glove.
