Optimum (3873) Opti-Glass Clean & Protect - 17 oz.

I was so happy with OPT's ONR wash and wax so I gave this a try. Cleaned up a couple weeks of winter mess and rain easily.I didn't do the passenger side of the windshield so I could compare it to the RainX wash fluid.After a weeks of drizzle I finally got to drive in a moderate rain on the Freeway. It out performed the RainX, not by leaps and bounds, but it is better. I gave the windshield a shot of the RainX wash fluid and the OPT still did better then the RainX.

It cleans, and it's decently hydrophobic at first, but I went back to rainx. This stuff only stays hydrophobic for about a week. Rainx gets me by probably 2 months between applications. Also it's advertised to users with opti glass pro as a way to make the optiglass pro last forever. Well, no. That is BS. I had my windshield coated with optiglass pro and it was great, then used this product to "maintain" it and then a week or so later i have to use my wipers even on the highway because nothing is beading and running, it's like i have no coating at all anymore. So i end up needing to re apply this cleaner product every week. Very disappointed in this product and the optiglass pro too. I went back to rainx.

Easy to use and very effective. Use it on the windows and the all glass roof of my new Model 3 and it gives me a streak-free finish.

Love all the Optimum products and the Opti-Glass does not disappoint. I'm using this over the top of Carpro Forte glass coating and gives it just that much more sheeting on the glass. Great stuff!

It’s a glass cleaner. Nothing more; nothing less. Very overpriced for what it is. Will not purchase again.

This stuff cleans great; no streaks! Definitely will buy again.

Tried this after using a different product for years. Glass looked great until I drove in the rain - it seems to leave some residue on the glass, left my windshield cloudy and streaky with every pass of the wiper blades in the rain. Thought at first it might have been the wiper blades getting old so I replaced those with no effect. Took a couple cleanings with a different product and lots of driving in the rain to get a nice clear windshield again.

This does not come as pictured. The bottle does not come with the nozzle. I went and bought a nozzle, subsequently, the bottle tilted over and all the contents leaked out. What a waste. The solution does seem to work, but it was an expensive application since I only got one use out of it.

Just like all there products excellentI use it on uncoated glass no streeking water beads off

So far, so good for a better view outside on dark, rainy nights.

Using it to detail exterior car windshields and glass great results
