Unger Professional Streak-Free EasyGlide Glass Cleaner Concentrate, 32 oz – Ammonia-Free, Makes 25 Gallons of Solution , Safe for Tinted Windows, LOW-E Glass, Windshields & Mirrors

Works as a general cleaner. I doubled the concentration to make a cleaning solution for my kitchen. Cleans with no residue so far on my granite. I've also used it on my laptop and stainless appliances and it worked very well. At the recommended concentration it does clean glass. Not as conveniently as Windex with cloths/paper towels as it doesn't evaporate as quickly as ammonia. But it does clean the glass. Probably best to use a squeegee. Very economical alternative to standard window cleaner.

Great value! I have always used conventional window cleaner and rag. This took sticky tape off my window easily with the recommended concentration.

I purchased this soap along with the entire Unger system of pole, squeegee and bucket. No streaks! A great product with a pleasant scent too.

Having glass sliders,this is a must. Clean very well. You only need 2 capfuls! This will last a couple of years for me!!

Works very well. Removes dirt with no streaks or smudges so long as you do your part with the squeegee.

Really good window cleaner, no streaking.

Works great

To achieve the best results with this product, it's essential to follow the specific instructions carefully. While it is possible to achieve a streak-free finish, using waffle cloths—as recommended in the video—is crucial. I found that I needed to put in quite a bit of effort. After applying initially and wiping dry, I had to go back with a small amount of the product with a microfiber cloth, I had to go over the surface again with the waffle cloth, lightly moistened with water, to eliminate any streaks. So, is it streak-free? It can be, but be prepared for a bit more work than it initially seems!
