Simply the best glass cleaner I have ever used! paired with the auto geek micro fiber cloths for glass, you will have the cleanest streak free glass you have ever seen, almost effortless!!

Sonax just makes great products and this glass cleaner is no exception. Coupled with the Speed Master glass cleaning towel, the task takes far less time. I clean the glass with a standard towel if needed and follow up with the Sonax and Speed Master for the finish. Very satisfied with the results. One interesting feature of the Sonax is it definitely makes it a bit harder for bugs to stick. Not perfect by any means but they appear to come off much easier when using the wiper/clean function. Definitely going to look into getting the concentrate additive for next spring's but season.

This is an excellent glass cleaner. There are others out there that are very good also but this is my constant go-to because it performs so well so consistently. Paired with a short pile microfiber or a waffle-weave glass towel you will have great results. A little goes a long way. Also effective on Nav screens.

I like this product. Does a nice job so far.

While I think this is some of the best window/glass cleaner I have used it did not resolve the issue with my windshield. For weeks I had a light fuzz or lint on the windshield (exterior) that I could not remove. So to get help I asked a local detailer for help and they were gracious enough to advise me on what to do.

I used a compound and steel wool to remove the windshield contamination followed by a mixture (2 oz. to 1 gal of distilled water) of Optimum no rinse wash and wax. This was the cure for my issue.

NOTE: I used short pile microfiber towels, I found it was NOT necessary to use a specific glass microfiber towel.

I continue to use SONAX as a daily glass cleaner and it performs well.
