Unger Professional Streak-Free EasyGlide Glass Cleaner Concentrate, 1 Gallon, Ammonia-Free, Makes 100 Gallons of Solution, Safe for Tinted Windows, LOW-E, Windshields and Mirrors

I'm amazed at how clean my windows are since I started using this. It is extremely concentrated, only requires 2 capfuls (which are small) in 1 gallon of water. Removes hard water spots too. No streaking.

I'm a professional cleaner and I have used all of the window and mirror cleaning products out there and this is by far the best glass cleaner I have used on my own cleaning company and I hate streaks. They are my arch nemesis and this glass cleaner goes above and beyond anything. I refer all my friends and family to it because it is the best and all you need is two little capfuls and a 16 oz of water and just the best. Can't say enough about it it's great Can't say enough about it. It's great

This is the best product I have ever used on my windows! I have a dog that insists on putting her nose on the sliding glass doors. I’ve tried other products but nothing works like this. It took the doggie spit right off. Now to clean my bugged windshield

Works very well. At Two capfuls per gallon, it will last a long time. Well worth the m.

Three weeks ago we moved into a house on Hood Canal, a portion of Puget sound. The windows were caked with salt spray and dirt. I dreading washing the windows. After looking at many reviews I decided on Unger window washing products. Let me tell you, I'm so glad I did. From the cleaning solution to the 2 in 1 window washing tool everything works perfectly. I also purchased their collapsible bucket along with microfiber towels. My windows look like a professional window washer did them, streak free and spotless. Unger products made an undesirable task much more tolerable. I will recommend their products to all of my family and friends. Thank you for selling products that really do the intended job.

Much better product than I expected. Very pleased with the results. Instead of spraying it on I mixed up a small buckets worth and applied with a sponge. Squeegee to finish and my patio doors look great.

This is a great glass cleaner, with very little odor, and it doesn't leave streaks. The fact it's a concentrate is even better, because it's far superior than other glass cleaners and this will last me a while. Make sure and use distilled/bottled water to mix it... works better.

That's about it. for many years I've used a window cleaning solution made locally by a family owned janitorial supply that had been here for as long as I have (Bradley's Janitorial Supply, Escondido, CA) It was a highly concentrated 'Squeegee' cleaner which resembled a very heavy but NOT soapy syrup. A couple of capfuls and if you wanted a dash of clear ammonia and you were all set. Well, the place went out of business in the last couple of years, so I've been searching for a replacement. Being familiar with Unger as one of the most well known window cleaning suppliers, I tried this cleaning solution here. Sorry, not impressed... Basically is has a very heavy but pleasant perfume in it. The deal is, that window cleaning solution has to be strong enough in order to clean properly and as a bones HOPEFULLY be slippery enough for the squeegee to glide effortlessly over the glass. Well, it cleaned 'Okay', but there was what I felt a lot of drag on the glass. So, I added more, thinking that maybe that would make it more slippery. Nope... It just made wiping the excess off the glass EXTREMELY difficult, and it would not wipe off. Too concentrated. So, it the actual cleaning power is very average. It is NOT slippery enough to make using a squeegee glide over the glass like it should. And, if you add more, on the edges where it might dry, when you try to wipe it off, you can't. Not really that great, so I threw the bottle away although nearly full. Most definitely ***NOT*** recommended by someone who has owned a window cleaning business going into my 45th year now. I've never been a big fan of the 'Joy' approach due to its drying so quickly in the sun. I'm gonna try the new Basic H2. I had used the original Basic H in the past and it worked great, so we'll see... ***EDIT Okay, I just thought I would come back here and mention how it went with the new Basic H2. Well, it was great! A ***HUGE*** improvement over this Unger cleaner, I must say. So, I just HAD to come back and let whoever wishes to know, that the Basic H2 is a TREMENDOUSLY better choice! Like I had mentioned earlier in my review, I've been doing this professionally as an owner with my Dad in this family business going on almost 45 years now. So, for whatever that is worth... :D But yeah, the Basic H2 was awesome! I mixed about half a capful in about 1/2 to 2/3 a pailful of water, maybe about 2 gallons. Bloody perfect! The nice new, Sorbo squeegees glided effortlessly over the glass, just like it is supposed to do. But, the nice thing was that when I went to wipe the edges where it might have dried a little, it was wonderfully EASY to wipe that excess off, even where it had dried. UNLIKE the Unger above. So, win-win both ways. Now, the REAL test of course would be in direct sunlight. Because there when it dries very quickly around the edges and then you go to wipe it off, that is where for example the disadvantage of using Joy comes in. But, just in the shade where it had dried somewhat, it came off beautifully with a towel on the edges. So, I think I've found my new cleaner (which really I had discovered the original Basic H a long time ago but had kind of lost track of it) Basic H2. DAMN good stuff! HIGHLY recommended. Less money, more concentrated, extremely more gliding ability for the squeegee, and the dried edges easily wiped off with a towel. There you go! : )

Love this stuff, great window, glass cleaner. No streaking

I absolutely hate washing windows. For me, it always involves too much effort with mediocre results. I actually put a real effort into it too! Lol. Took a chance with this product since the price seemed a bit high--it isn't since it's very concentrated--and I am thrilled with the results. Minimal effort and crystal clear, streak free windows. Zero of that frustrating film that other products leave. Outstanding product!!

Great item, works amazingly well…no streaks

This stuff in general works well, however for one of my windows that gets sun almost all day and had some sun baked water spots on it for about a year, this cleaner could not remove it. I had to get a ladder and windex with a rougher cloth and scrub to remove the spots. For regular dirt, dust, etc this cleaner works very well with no streaking

Cleans your windows, minors with no streaking. love it %100 , easy to use and you need to much of it
