If your windshield is damp, just wipe surface with Cadie No-Fog Mitt.
Amazing mitt is treated with a special formula that works against future moisture build up on glass, mirrors and car windscreens to stop the fog!
Active fog fighting ingredients last as long as the mitt.
Sudsing action tells you that chemicals are being released.
If no moisture is present, dampen one corner of Mitt before using. Always wipe until glass is completely dry.
