Things You'll Need:
- Soapy water
- Ammonia-based household cleaner
- Paper towel
- Hard water mark remover
-
Step 1
Apply some dish soap to a sponge, rinse it lightly with warm water and use some elbow grease to get the stains out.
-
Step 2
If that doesn't suffice, treat the stain with a standard ammonia-based household cleaner. Don't use window cleaner, as it may alter the surface of your Corian counter.
-
Step 3
Dry thoroughly with paper towel when you're finished. If standing water dries on Corian, it can leave behind a blotchy residue mark.
-
Step 4
Remove water stains on your Corian counter with any product designed for treating hard water marks.
