Wolfgang Concours Series WG-4300 Glass Polish, 16 fl. oz.

I first purchased a glass cleaning clay for glass- and it did not do anything to remove bad water spots. Then I tried the Wolfgang product, and it is AMAZING. Easy to use, and removed all spots. The windows on a 2006 car- look new. Finally a product that lives up to what it states it will do.

Worked as expected.

When a little bit of elbow grease makes a difference, this is the product to use. I used it on barrister bookcase glass which has been in storage for over 20 years. It removed tape debris, clouding from "instant" glass cleaners and gave the glass a completely brand new look.

Excellent polish once windows cleaned with standard cleaner that gets off all calcium software deposits and road grime., Simple to use with foam applicator and then immediate wipe off. Live in Tahoe at did the job in weather at 34 degrees and product still buffed on easily. Driving at night is markedly enhanced and crystal clear without any refraction of oncoming headlights. Water from rain and or snow seams to follow off easily once polish has been applied. I will buy more and like use this twice a month to maintain pristine windshield status. Used it all over my car including sun roof glass and all windows inside and out.

I would only use it on old auto glass that took some punishment over time. There's not much to like about this product. It ruind my year old cars windshield. I've been detailing cars for 12 years now, and i realize that its a problem to find good glass polish that wouldnt leave tiny scratches all over your glass. Companies that make glass polish should test it on their own cars before they sell it. I used it with meguiars soft polishing pad on rotary, low speed, to get rid of road film and some hard water spots, glad it was my own car not customers! Yeah it looks great in a garage, but once you take it out on sun - its bad. Do not recommend using it on new auto glass. Using fine compound made for paint correction is much safer on glass then this. And if you got some paint overspray or minor contaminants on glass just use steel wool dampened with all purpose cleaner 4:1(4 water, 1 apc), cool glass, in shade.

I have used this product for years, it is a excellent window cleaner. The bottle I received must of been on the shelf for quite a while. The cleaner was the consistency of mud. After 20 minutes of shaking, it would not pour into my pump container. I threw it in the trash. Beware of these third party resellers with outdated product!!!

I was pleasantly surprised. Hard waterspots have been driving me nuts on my truck windows. I tried a couple different glass cleaners and a few suggestions from the web with no luck.This stuff worked 100% on the first try without nearly as much polishing as I was thinking. I lightly buffed it on and wiped it off. Problem solved. Nice to see a product that does what it says for a change!

I actually use this to shine my collectible antique glass. I just make sure that the glass is wet before I rub it on. I rub it on like a thin layer of was and let it dry a bit. When I buff it off the glass shines like new. Great product.
