Windex Outdoor Window and Glass Cleaner for Hose Ammonia Free, Concentrated Formula for Deep Outdoor Clean, Patio Cleaner, Compatible With All Hoses, 32 Fl Oz (Pack of 2)

This product is SO easy to use and cleaned my very large windows with very little effort and very little time invested on my part. I would highly recommend.

I live in Hawaii, near the ocean so saltwater spots are a continuing problem. Have tried other products with varied success. This product works great. Windows are clean and streak free. To be on the safe side I squeegeed the window panes to ensure a streak free result. The screens were left in to see how well it would clean. Cleaned well, some of the windows behind the screens had water spots. Because those windows can be removed and rewashed to remove spots it is not a problem for me. Will definitely continue buying this product.

Product works great so long as your windows are not very dirty. This cannot replace the need for hand scrubbing if that is what is needed. I use it twice a year in the spring and fall and my windows are sparkling.

This product is incredibly easy to use and works great to make your windows sparkling clean! The only downside, is they get so clean, birds no longer realize the window exists. We had a bird hit the window so hard after cleaning that the bird was significantly concussed. Now most of the time the birds fly away shortly after, but our window was so convincing of it being an open air space that this bird hit it at full speed. The bird subsequently had to be taken to a wildlife rehab center for recovery. Needless to say, you may spend more time on bird rehab, but your windows will look great.

I buy this every year. So easy to clean the windows from the outside. great value and so helpful to get the job done in one day

Ok -- I'm going to do my best to give a lot of detail and be completely fair.We live near the beach. Like, 75 yards away in a straight line and we can see the water from our front and back porches. Beach air is a thing.Our house is new construction. ALL of our windows in the whole house are big. Like, 4 ft tall X 6 ft wide. ALL of them. (Well, I take that back. The two on each side of the back door are only 4 ft X 4 ft). So there are a lot of individual panes.This is the first cleaning after construction. And we are (basically) on the beach.I followed the instructions EXACTLY. I was careful with the timing (at least 20 seconds of cleaner) and I was careful with the recommended soak time (about 3-5 minutes), and very careful to not allow the cleaner to dry on the windows.The first pass -- I'll write that one off to me not fully understanding the process. The second pass -- I started noticing a pattern. (I started with the 2 giant windows in our corner bedroom). The top of the panes seem to clean well (or at least better) as compared to the bottom of each individual pane. I thought that was really strange, given that I was extremely careful to make sure I put the same amount of cleaner on each part of the pane. But, gravity is a thing, and it all ran down the pane. But -- that would make you think that the BOTTOM would be cleaner. But -- nope. The tops of each pane are noticeably claner.Third pass -- I then moved on to the big window in our living room. (We have a giant front porch that goes the full length of the house, so all of these front windows are not ever exposed to direct rain/sun/etc.) .. The living room window --- it is ...OK...at best. It was not as bad as the bedroom windows. It is ok -- but it still shows the same pattern --- the top of each pane is cleaner than the bottoms.The reason that I'm trying to use this instead of cleaning each window manually is 1) The size and number of windows, 2) I am a total clutz trying to climb on a ladder for these 8 gigantic windows, and 3) we have security bars that will make trying to reach in to get the individual panes a real....well...pain. (The bars would take longer to remove than the cleaning would take.)My next attempt will involve possibly using a miniature mop (like the ones used with giant BBQ grills) to reach between the bars to wipe each window after the cleaner is sprayed on. THEN rinse. But, that kinda defeats the purpose and is not what is advertised by the manufacturer.So, in all, I probably won't buy this again. BUT -- I WILL definitely keep the bottles (the spray mechanism is pretty awesome) and make my own cleaner to go into them. If I'm going to have to do extra work anyway, it doesn't make sense to pay more for a substance that doesn't alleviate that need, even though it advertises that it will.TLDR: Good, but not great. Tops always cleaner than bottoms. Repeat application seems to help, but isn't consistent with the results that the manufacturer claims.

I am impressed with the hose hook up system and the ability to switch from soap to rinse without shutting off the hose. Used it to wash solar panels on a 3:12 roof pitch rinsing first, they washing with the soap, scrubbed them with a long handled soft cloth brush and then rinsed until the soap was gone. Beautiful, clean and ready to suck up the sun solar panels were the end product. Just a caution to remember when washing solar panels - do it when the sun is not beating down on the panels, cloudy afternoon or early morning I always find best.

I have used these before.I got these to use this spring. Cleansthe windows better than I evercould by hand.I don’t do windows.
