How do you get a water mark out of a blind?

To remove a water mark from a blind, start by gently wiping the affected area with a soft, damp cloth to lift any residue. For fabric blinds, you can use a mild detergent solution, applying it with a clean cloth and blotting, not rubbing. For vinyl or aluminum blinds, a mixture of vinegar and water can help; spray it on and wipe with a soft cloth. Always test any cleaning solution on a small, inconspicuous area first to avoid damage.
