1. Prepare and dry dust
Before introducing any moisture, remove loose dust from your blinds to prevent it from turning into a sticky residue. Close the blinds so the slats are flat, then use a vacuum cleaner with a soft brush attachment or a dry microfiber cloth to gently remove dust from top to bottom.
After dusting one side, tilt the blinds to the opposite angle and repeat. This thorough dry dusting helps keep dust from mixing with water and forming a difficult-to-clean paste.
2. Mix cleaning solution
Fill a bowl with warm water and add two to three drops of mild dish soap, stirring gently to avoid excess suds. Too much soap can leave a sticky film that attracts more dust.
If your vinyl or aluminum blinds have greasy buildup, add a small splash of white vinegar to the solution. Avoid vinegar on real wood or sensitive surfaces, and never combine vinegar with bleach or chlorine products to prevent harmful fumes.
Dip your cleaning tool—such as an old sock or microfiber cloth—into the solution, then wring it out thoroughly so it’s damp but not dripping.
