Full Crystal Window Cleaning Kit – 4 oz Glass Cleaner and Bottle with 27 ft Reach, Makes Up to 640 fl oz, Cleans Up to 20 Windows, Scrub-Free, Rinse-Free

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.

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.

This is an amazing product and it does what it claims. It makes easy work of a dreaded chore. Only thing is that it does not clean up to 20 windows as advertised. It takes about twice as much to do that. Still it does a good job

First of all, some of the reviews illustrate how people simply do not read directions and have no idea how to use this product. Mechanically, it worked very well. Distance it goes up entirely depends on your water pressure, but it will get 20-25'. Now for the review: Ease of application: It really is easy - wet surface, apply soap, wait 30 secs, and rinse. Location: Lake house in Northern Illinois. Cathedral ceilings 20' up. Tons of windows. Last cleaning: About 4 years ago (this may be a contributing factor) Application conditions: Early morning temp 68-74, not in direct sunlight. Water: Well water softened using salt. This is a soap with a sheeting additive - as a result, it is slippery. The bottle can be hard to hold onto when it is soapy. No big deal, just shift your grip or use a towel around the outside. Efficacy - how good does it do? This simply will not get your windows as clean as conventional towel/Windex. That is the honest truth. It leaves a slight coating on the surface that my wife hated. I didn't mind (you know where this is going). However, it did visibly remove dirt, and cleaned up pretty good. Again, not to my wife's satisfaction, but I could live with it. We tried 2 and 3 applications after the first dried - got better, but still left the film. Bottom line - if your not picky, it works pretty good. If you are picky, go with Windex and towels. The whole house cleaner again did pretty good, but a brush will do it better. Same issue.

We have hot water on-demand with the temperature set at 120°F. I let the water run until I saw steam, then filled the jug. I poured in the crystals and stirred them a bit as it didn’t look like they were dissolving well. I started applying the solution to the windows. I did not like that I needed to have my finger on the hole, as the hot water or steam was burning my finger. The first few windows the applicator was generating sudsy water on the windows. But after that it wasn’t. I looked in the bottle and all the crystals had settled there. I tried to stir the solution again, but it had hardened into a solid mass. I needed to chop it up with a spoon to get it out of the sprayer. Obviously the water coming out of the faucet was not hot enough to dissolve the crystals. So I heated some water and used that. Even with heated water the crystals did not dissolve immediately and I needed to stir it for quite a bit for them to dissolve completely. I now had another issue, the bottle was too hot to handle without a pot holder. So I carried it outside with a silicone pot holder. The solution was nice and sudsy and I applied it to a few windows. I noticed that when I covered the hole, sudsy solution was not coming out. When I opened the container to see if there was some type of blockage, I noticed that the uptake straw was melted. I would prefer a premixed solution or a liquid that has to be diluted. And I don’t like that I have to keep my finger over a hole to have solution be applied.

This product does work very well, just follow the instructions. Place finger on the hole to activate the cleaner, WITHIN 30 SECONDS, rinse. Remove finger from the hole and it will dispense water to clean off the chemical cleaner.

Amazon took care of the shipping error on the product where we only recived one bottle and a packet of the solution. So we recived the order correctly as Amazon came through with sending correct amount purchased. The product is great stuff and would recommend using it on your home or RV.

This product did not leave my windows clean without streaks. The windows with screens have water spots. The sprayer is effective, but the windows all need to be redone.

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.

Falsely Advertised as safe and non-toxic, safe for plants etc but actually when you read the slew of chemical ingredients and it says disclaimer/i warning “don’t get on skin, wash immediately and thoroughly , don’t inhale, don’t get in eyes, etc. I wouldn’t call that safe and non-toxic.

Easy to use and worked.

Excellent product!!!
