TVTime DirectCadie No Fog Cloth

I guess it is simply putting some soap on the glass. So the water runs down the glass as opposed to not "fogging" the glass. I also tried on the outside of a window where the inside AC causes water to fog the glass when the due point is above the AC/window temperature. It does not work at all. So it may help a little on a bathroom mirror, but there is no magic going on here.

For me it did not work. Wait till something is fogged up to use it to prevent fogging up.

It works! And as long as it is kept sealed it will last a long time (can be used several times).

This is my third one. Each previous one lasted for 1-2 years. love it.And their customer service is the best!

These are a waste of money.They made better ones many years back.They're anti fog clothes.

Worked well, left a slight film on the inside of the windshield though but it did make dealing with the fog issue easier.

Amazing. One wipe with this cloth (bathroom mirror) and the fog is gone - no streak, no lint

Bought this on the way out of a store with same low expectations we had from other anti-fog products to use on our camper windows for snowy winter camping.It is the best we have found.
