Absolutely no streaks left on one swipe either glass window or mirrors,Excellent product!

No streaking, gets rid of pet slobber without much fuss

This glass cleaner does a fantastic job of leaving windows and mirrors streak-free and crystal clear. It cuts through smudges and fingerprints with ease, and a little goes a long way. The bottle design makes it easy to spray evenly, which helps with coverage. However, the scent is quite strong and lingers for a while, which may be off-putting for those sensitive to smells. Despite that, the cleaning power is top-notch, and it gets the job done without much effort. Overall, a great cleaner if you're not too sensitive to strong scents.

Es un súper limpiador de vidrios a diferencia de otros que dejan como grasoso y no disuelven bien la mugre en vidrios. Lástima que se a muy caro en relación a otros productos

This glass cleaner works well. It's not entirely streak free, especially if using a paper towel, but it cleans great and leaves no streaks if you use a microfiber cloth. Has a faint not unpleasant scent that does not linger, much better than vinegar based cleaners both in smell and finish.

The Zep Streak-Free Glass Cleaner is excellent! It leaves my windows and mirrors crystal clear without any streaks. The 32 oz size is great value, and the blue color is a nice touch. It's easy to use and works quickly. Highly recommend for spotless, streak-free glass!

Compared to other well known brands, this is a great window cleaner. I purchased it because it was a great price on a lightning deal and it cleans well and leaves no streaks.

This works great. I also like the price.

It does what it says on the bottle.Quickly breaks down muck.

Update again: Well, I figured it out. I needed to shake the bottle. Now it smells absolutely terrible but does its job. 5 stars, ignore everything below.UPDATE: WOAH WOAH WOAH! I just posted this review and I noticed that the price is nearly $10 for one bottle. You have to be mentally ill to pay that price. If you did pay that price, I truly pity you. It's not worth $2.00, and $10 is abominable. I mean let's be real. It's colored water with a little bit of stuff that is unhealthy for your eyes, mouth, or skin. It is utterly useless, and I would be angrily returning it if it had cost me $10. For $10, I wouldn't have even considered it. I mean come on!I had really high hopes for this product, although I'm not surprised by the result. I paid less than $2 for a 32oz. bottle of this stuff as an "add on" item. It was even cheaper than buying the name brand blue liquid at the store.I live in a dorm and I am using a glass desk. Unfortunately, this desk is a magnet for fingerprints, and I like to keep things clean. Water wasn't cutting it, and I was running out of my normal glass cleaner. I thought I'd give this a try. It was dirt cheap, and it seemed to be doing its job for other users. All I had to remove was fingerprints, and this could be done, with more effort, using just water. This cleaner arrived [stupidly] in a box you might find a toaster oven in. This surprised me, because there was more than enough room in the other box of items it shipped with. Whatever, it arrived safely. I was eager to try it out as I had already ran out of the other wind- brand, and had been using water. I eagerly cleared my desk and sprayed some of this stuff on it. I was confronted with a much less breath taking smell than I was used to. I wiped it around on my desk, and was disappointed to see that it seemed to be turning my fingerprints into a smeary mess. Confused by this, I figured I must be using a dirty cloth. I grabbed a clean, white, cotton cloth and tried again. I found that it evaporated quickly, but just left smears everywhere. It actually left my desk looking worse. I tried paper towels, and microfiber, the latter of which seemed to do the job, but as soon as it dried, there were the streaks. In the end, a wet cotton cloth did a better job. I also tried this on my mirror, and it was the same story. Using the same cloth with just plain water did an equal or better job.Maybe I'm more fussy about my glass than the so called "commercial" users. If it can't remove fingerprints and smudges, I don't see how anyone would find it useful. I also don't see how anyone who has used the other blue wind brand could settle for this. It says it can remove grime, but it is no match for fingerprints. I paid less than $2 for it, and I'm humbled by how ineffective it was. Even at that price, I am unimpressed by its sub-mediocrity.What a shame. With all those warnings, I probably shouldn't pour it out. It will most likely be forgotten about in the far back corner of my room, behind the trash bin.I don't know what compelled me to write this review on such a mundane product. I just still can't believe how miserably it has failed. The only value I see in it is the bottle. It seems to be made of a sturdy plastic, and the sprayer nozzle has an "off", "spray" and "stream" setting. If only I could find a way to responsibly dispose of the liquid, I would buy a bulk jug of the generic, store brand blue chemical crap and use that instead. The bar has been set so low, blue colored water would suffice.For $2.00 though, not much can be expected. It cost less than a normal spray bottle on amazon. If you want a decent quality spray bottle on the cheap, this could be an option. The liquid inside is just a mild inconvenience.Spray bottle: 4 starsCleaner (I use this term very loosely): 0 starsAverage: 2 stars.
