Simoniz Platinum Anti-Fog Interior Glass Coating Spray, 473-mL

This product is very easy to use. The spray function is powerful but not overwhelming. It applies exactly where you spray it. I used it on my childrens car. I sprayed a bit on the inside of the windshield and used a piece of paper towel to wipe off the excess. There was no residue left behind. It was very cold out when I used this product, but the windshield did not fog up. I believe this product indeed worked. I will be using this spray from now on.

I received this free sample to try out. At first I never knew such a product existed. So I tried it and was amazed what it did. I didn't want the inside of the vehicle to not fog. Usually I'm hot in the car which causes the windows to fog and my view becomes minimal. But once I tried this product my viewing while driving was way much better.

We tried this product in my boyfriend's car. First of all, this is so easy to apply and leaves no streak on the windshield. We waited a couple of days to see if it worked. We usually have a lot of fog problem in winter in our car. To our surprise, we did not have fog since we applied the spray. This product delivers his promise. I could not be happier to finally having found a solution to our problem. I'm not sure how often to reapply the product yet, but given the size of the bottle, I believe one bottle could suffice for the winter. I recommend this product to everyone who lives in cold weather and owns a car.

I really wanted to love this anti-fog spray but it fell short on the stars for me. I tried a couple times (with paper towel and a cotton cloth) to get the application right and followed the directions exactly but the spray does leave a film on the glass and its very distracting especially when driving at night. As shown in the picture, the film leaves a haze that affects light and your view when driving which is a deal breaker for me. I will say that it does help lessen the amount of fog especially going from the cold outdoors to a heated interior. I feel like this would be great to apply to side or rear windows where a slight film wont impact your windshield.

Thank you @canadiantire and @thisisbutterly, for giving me this free product review opportunity! The Simoniz Platinum "Anti-fog interior glass coating spray" came at the perfect time...Winter!!! I always seem to battle fog in my 4-Runner. The only way I can get rid of it is if I sacrifice the heat from me and blast it to the windshield. I went ahead and applied the product to half my windshield and driver's window, leaving the passenger side windshield and side window untreated. I wanted a true comparison test. Due to the lack of fog in my few days of running around, I improvised in my testing. I placed a hot beverage on the passenger side of the dashboard first. I left it for 30 seconds, and it created an immediate visible thick fog line going up the windshield. I moved the hot beverage to the driver's side of the dashboard and left it for 30 seconds. This created a bit of fog, but it was almost see-through and did not instantly spread up the windshield like the other side. The overall spread was smaller, shorter, and one could almost see through it compared to the untreated side. I did not apply the product liberally as I should have, as this was my first time using it. However, overall, this product provided a dramatic improvement in visibility compared to the untreated side. Thank you! I will be using this throughout the year!
