1. Prepare blinds
Make sure the blinds are fully extended before starting and that the material can be wiped down with a damp cloth. If unsure, check the manufacturer's cleaning recommendations. These steps below will refer to cleaning of most styles of blinds.
2. Dust blinds
If dusting blinds, make sure the slats are turned flat or the blind is fully extended / lowered, and dust from top to bottom. A Vacuum set on low and with a brush attachment can also be used. Do not rub any marks or stains at this stage.
3. Check blinds for marks
After dusting, or vacuuming your blinds there may be some dirt particles still on the blind. This is where you can use a damp cloth to spot remove the dirt. Be careful to not rub in one spot as this may remove the fabric coating and if using a mild detergent test it in a spot not visible prior to removing the dirt to make sure colour is not effected. Do not make fabric wet. Wipe in a circular motion without putting too much pressure on the fabric.
