Full Crystal Window Cleaner, Bottle + 16oz Powder, Cleans Up to 80 Windows

Bought this to clean windows of 3K sqft ranch AFTER applying Wet & Forget Roof & Downspout Cleaner. (expecting those products to splatter on the house & windows during application) You'll see in other ratings how people moan that this product does not leave windows "spotless" or anywhere close to hand-washing. They're partially correct. Stress PARTIALLY. If you're talking about a typical urban / suburban home with years of that filmy-urban-suburban build-up on windows and screens ( that soupy mix of auto exhaust combined with several mos per year of intense humidity ) ... And if you're tasked with cleaning high-up, 1/2-2nd story windows, paladian and/or transom windows? YOU REALLY CAN'T GO WRONG WITH THIS PRODUCT! In all likelihood, you won't see "spotless results." But you'll take a lot of dirt off. You'll notice a cleaner window overall. And you'll save A LOT of money not paying someone $500-$2K to clean the same windows. WHAT I LEARNED / AFTER A FEW HIT-OR-MISS BLUNDERS (costing me 2 packets of solution) 1. Prep-Work is EVERYTHING. Mix the solution with hot water at least 40-60 mins in advance (it doesn't mix very fast even with hot water!). 2. Set the solution aside while setting up hoses and any other necessities. (ex. Ladders if you're spraying higher than normal) Be sure that your water pressure isn't diminished by attaching smaller hoses after larger hoses. And test-spray how far you can spray BEFORE you start. 3. TAKE NOTE as to whether the water pressure is lower-than-average (Ex. Saturday or Sunday in Late Summer, when everyone is watering grass & washing cars = probably not the best time to apply product BECAUSE you cannot spray as far) 4. NOTE THE TIME OF DAY. I've sprayed the product at dusk on a hot, super humid evening. < NOT THE BEST IDEA because the windows would fog up with the AC being in the high 60's. You you’re your windows to be BONE DRY after you apply it. Otherwise, you might be spending $$$ on a do-over, getting less for your initial money spent. 5. Keeping the overall context in mind – and realizing that you’re cleaning years of build-up off screens AND windows… Half expect to redo the windows if you’re not 100% satisfied with the results. Considering the price paid, no product is going to remove YEARS of build-up COMBINED WITH very little physical exertion. 6. BIGTIME Grain-of-Sale on the Infomercial claims of “clean up to X number of windows per packet!” I found that –after going through 1 entire packet screwing things up – 1 packet can maybe do 7-10 windows max. But hopefully my advice above will save everyone the hassle that I encountered.

I actually hired somebody to wash my windows with this stuff for me. She did a great job and my windows look excellent. I hired her a couple years ago to wash the inside of my windows. When she had finished washing my windows a couple of days later I looked at all of them and they were just clean as could be. I have quite a few windows in this house, 30. That's including splitting the big Windows into two. Because they are two different windows just in one Big Frame. So I would highly recommend this product. It only took her a couple hours to do all of them. It was well worth it to hire her rather than hiring a company come out and wash all my windows. I saw my neighbor and he had some young people there cleaning his windows and it was kind of funny. He was actually showing them how to use a stick to push up on a window to get the cloth on it. There was about two or three at least of them working on his windows. And he had to show them how to do it. I actually changed the formula in a sense. I put one of those bags in a gallon plastic bottle and filled it with water. Shook it up. And then poured it into that spraying device. It cleaned the windows just as well as the original formula. I still have one bag left over. She even sprayed the windows on my car. I have a very tall house it's 24 ft to my roof and that spraying device worked great on my windows on the second floor. The only problem I had was that the windows weren't locked shut and some of the water got into them. But she went up there and made sure they were all locked up and cleaned up any water that had gotten through from the first time. I have nothing bad to say about this product it's sprayer I think it's a good product and it's well worth the money that you pay for it. It's easy to use and it'll save you money in the long end. The product didn't excellent job and so did the woman that I hired. It was easy enough for her to do I had one of those hoses that gets all the water out and shrinks up so it was easy for her to carry.

1st works great, used on windows that hadn't been cleaned in 2+ years. The only reason for 4 stars is as stated in other reviews "you need hot water to fully dissolve the mixture" - but a word of caution: I used hot water from a hot water pot, still difficult to dissolve, but worked eventually. The problem I encountered was the suction tube will act like shrink tubing when exposed to very hot water. I remedied this by replacing the "shrunk" tube with a piece of weed eater fuel line of the same size as the original. If you follow the directions it does a super job cleaning the glass. I would buy this again.

This product was highly recommended by company who redid our screens. We replaced our west side screens with higher sun/heat protection screening. The new screens cover the entire window and are screwed into the frame, so they aren't removable. We followed the product instructions closely (also per Amazon customer feedback) and started cleaning. Attaching the sprayer bottle to the hose required attaching the lid to the hose first, then screwing on the container to the lid, which was a little cumbersome with the solution already in the container. It was easy to operate and wash windows, and the spray reached up 15 feet or so. Be sure to follow instructions and direction of spraying during rinse and wash phases! The windows and screens dried and everything is clean, but a few water spots remained on the glass. Overall, we think it'll work for our high windows, but one pouch cleaned 5 large (5' wide x 5' high) and 2 small (2'x3') windows, so we're not sure it's worth the price, but beats having to climb up a ladder on a very steep side of the house. We'd give it a 3.5 rating overall

I have used this successfully in the past but ordered a whole new set including sprayer. So far I have done 7 windows and am almost out of the second packet of solution. There is definitely something faulty. The windows are a little cleaner but there are many places that will have to be hand done. I also had to disconnect he hose in order to rinse windows every time because the bottle did not stop spraying soap when I removed my finger from the hole. Based on this experience, I will not buy this again. Very disappointed.

Full Crystal Window Cleaner fulfills its description of the product. The product is easy to use and leaves windows “Crystal Clear “ literally. I as well as my neighbors noticed the windows were sparkling clean and clear. I would highly recommend this product to anyone who wants their windows to be Crystal Clear.

This is an amazing product! I followed the instructions exactly and my windows are beautiful. I can't understand why there are so many negative reviews. Make sure you use really hot water and stir it until all the crystals are dissolved. Also, I applied the cleaning agent and counted to 20 then rinsed the windows. You can't leave it on for more than 30 seconds. I also applied it when there was no direct sunlight. The only thing I didn't like is that it barely reached my second story windows. I needed to use a ladder to reach them.

I had high hopes for this product but honestly it's disappointing. It did reach the upper windows. And it did cut through bird poo. However it leaves streaks. I had go back and clean the windows when done. You might want to skip on this product and just get a combo squeegee and sponge type unit. Wanted to post a photo but my camera didn't pick up the streaks well. The second time I used it I rinsed 2x. Streaks.

Follow the instructions on how to use the product and it cleans very very well. I have told 3 of my friends about it & only one had a problem with the bottle not working properly. Only one issue - a little on the expensive side.

Worked amazing! Not sure if the lower reviews were due to not following the instructions and honestly I was reluctant to try it. Seriously my windows are spotless and gleaming. I will most definitely buy again but the 2 packs are enough for spring and fall cleaning.

It work well and easy to use, cleans even through the screens. You need to buy extra cleaner, there is only enough for approximately 4 windows, in the kit.

We used Fuller Brush Co. Full Crystal Window & Outdoor Cleaner to clean the outside windows of our home on Yorke Peninsula. As we get what seems to be a very fine salty deposit on our windows we thought we'd try something other than just elbow grease. The product worked very well and was easy to apply. Thanks.

Did not work the way it was suppose to. Left water spots on windows and the screens were not clean. Very disappo
