If the dust has accumulated to dirt, then the best way to clean the blinds
is with a damp sponge, cloth, or paper towel. Depending on the dirt, it may be
best to take the blinds off of the window, and take them outside, hosing them
down, and leaving them to dry. If this isn’t an option, they can always be set
in the sink or bathtub, carefully cleaning them with warm soapy water. Let the
blinds soak for about a half hour, and wipe or hang dry. Make sure you don’t
bend the blinds and that they don’t scratch the tub.
Fabric blinds require a light vacuuming. If they are dirty, clean them with
warm water and spot cleaning where necessary with detergent. If you have wood
blinds, the best way to clean them is with a cloth and wood cleaner, a mitten,
glove or old sock on the hand or the vacuum cleaner. Washing them with water
isn’t suitable--this may warp the blinds. Recommended cleaning for blinds is
every 3-4 months. In order to keep the dust level in check, try to clean the
blinds when you clean the rest of the house so they will look beautiful all the
time.
