Guru Glass Cleaner # 1 Not A Good Performer...

according to my tests.



Bought 2 of them. Gave one to my cousin to try. Showed her the tests results. Kept one for myself.



Used it initially with bounty towels on my bathroom mirror and got lots of hazing and streaking. Cleaned it a 2nd time. Not much better. Used #2 rated cleaner and had a streak-free mirror. My cousin tried #1 on her car windows using a 3M Yellow mf towel. Same results. Used #1 on my car windows using a CMA Viper Power Scrubber and got the same lousy results. Cleaned each window inside and out (in the evening) under cool conditions. Then drove the car pointing the front windshield at a setting evening sun. What I saw was appalling. This turned out to be the WORST glass cleaner that I have ever used. Am I the only one?



Has anyone else experienced similar results? And this is rated #1?

Did I do something wrong? What is it with these glass cleaners? Never had any luck with any of them but this was one of the worst.



All comments are welcomed.
 
If Stoner's was the Number One Glass Cleaner...(don't have the report, don't plan on purchasing it)...but inferences have been made both here and at other forums that it was....then I agree completely...no matter what I tried Stoner's Invisible glass streaked inside glass terribly. I am sure that I have stated this in the past...probably in the archives. I have much better luck using Sprayway (which smells good too)(not sure how it rated). In fact I used Sprayway to clear up the streaks left from the Stoner's Invisible Glass cleaner.

I have found after that experience that final buffing with newspaper really cleans up any streaks left behind.
 
I use the #1 Rated cleaner and have had nothing but great results. It works just as the report describes, for me at least.
 
The first thing you must learn about window cleaners is this. There are many different formulas for window cleaners, and they are not all in one can. When you take brand A and try to clean a window and it doen't work and you follow it up with brand B. It was not that brand B was better. It was the combination of the two that worked. The chemicals in the first window cleaner cleaned the first set of films and the chemicals in the second cleaned the second set of films. They worked together with each having it's own strengths and weaknesses. This is why I recomend to always have more than one window cleaner on hand.
 
Regardless of any rankings, from my personal testing, nothing beats Eagle's 20/20 glass cleaner and a microfiber towel. Even when I am stuck working in the direct sun, I can get the windows to come out streak free. Just takes practice, I guess.

Really? Interesting... You have a PM. :)
 
I am not criticising anyone (Guru, Autopians, Mfgs) but I find it bizarre that any glass cleaning product can perform as the best for 1 person and then for someone else(s) not so good or poor. I've only been detailing cars (including windows) for 25 years so its not that I don't have technique, judgement nor experience. I mean to get streaks using #1 on a bathroom mirror in my house that has at worst some water spots, how do you explain that?



I did not have this problem with the Guru wax report. P21S was ranked highly and my own experiences and others here and on other boards confirmed this. Has ANYONE on this forum ever bashed P21S Wax?



I'm just looking for some rational answers. Is newspaper, steel wool, Viva or certain mf the answer? Again thanks for the responses.
 
Havent tried #1 or #2 glass cleaner yet . I bought a glass cl;eaner from the dollar store , its a vinegar alcohol and water mix, so far its the best glass cleaner I ever used.
 
The best way to clean glass is to take one microfiber towel, wet it and wring it out. USe that to clean the window and follow up with a dry, non linting microfiber waffle weave towel. I tried Invisible Glass, 20/20, etc, they all left a haze when the morning sun hits the glass at just the right angle. When using a wet MF, followed by a dry MF, there is no chemical residue left to haze. This method works on the inside of the car windows as well as the outside, as long as the car has just been washed. If you have road grime, bugs and other crap on the windows, this method is probably not the best solution. Try it and tell me what you think.

Great observation :xyxthumbs My "favorites" don't always work as well as I expect, but when I try a different glass cleaner- problem solved.



I plan to buy the glass cleaner test (if only to support their efforts), but like the wax test, for me it's just food for thought/interesting reading. There are SO many variables inherent in each individual application that NO test will ever be the last word on what EVERYONE should ALWAYS use.



BTW, I think it's cool that people are NOT spilling the beans as to how the cleaners ranked in the test.
 
Before I purchased the Guru Test Report for Glass Cleaners, I am already using the #2 product.



Indeed, the #2 product works great as reviewed by the report. But one thing I do not like about the #2 product is the fact that it has ACETONE CONTENT in it.



When I first used the #2 product, my hand got small blisters probably because of the ACETONE CONTENT (I might be allergic to it).



Since the #3 product is also available here in our country the Philippines, I purchased the #3 product and tried it. Based on my own personal use and observations, the product seems to be better by a small margin against the #2 product.



I carefully analized the #2 product's points / grade against the #3 product's points / grade and it seems the only reason why #2 was higher by about .03 points / grade from #3 is the Availability point / grade of the product which #2 product got an A Grade.



I now prefer to use #3 than #2 as it really works great on my Glass.



I felt so good purchasing the Guru Test Report for Glass Cleaner because it saved me $$$ by NOT ANYMORE PURCHASING the Two (2) highly popular glass cleaners being endorsed on this forum which did not get among the top 3.



The #1, #2 and #3 ranked products are not at all popular on this forum.... and they are so so so cheap! It really saved me $$$. The $3.99 I spent for the report was definitely worth it!

To my mind this is the critical point. We live in very different environments and are subject to varying problems effecting our cars. Sometimes is does take different products to get something very clean.



There is no perfect glass cleaner in the same way there is no perfect tire or oil
 
rad21,



You are so right about using 1 wet and 1 dry mf towel to clean the windows, i.e without chemicals. On my post from 7/6/03 'Glass Guru Test' post I reiterated the same thoughts. I also get great results on the windows after washing the car with Sonax or P21S shampoo and drying the windows with a P21 chamois or a waffle weave or my white bath-size Charisma towel or another mf towel. No streaks no hazing whatsover.
 
Sorry to hear that, Gint. It's odd because 10 people here, who were using products that they had no idea as to what they were, consistently put that product in the #1 position.



I've been using it on my car with great results as well...are you sure you bought the right stuff? From what I understand, there are two foaming glass cleaners from Bon Ami.



And, like I've said 1,000 times already, our reports are not intended to tell you to go out, buy something and then use it exclusively - they're comparative information on various products.



Again, sorry you didn't have the best results, but I'd double check to make sure you've got the right stuff, and if it is the right stuff - it just goes to prove that everyone's results will always vary. :)
 
geekysteve,



yeah, its the same can as pictured on pg 14 of your report.



I'm sorry also for I thought I found the ultimate glass cleaner.



I just bought DFT's glass cleaner. This was not included in the Guru Glass Test. Will try that next week against #1 #2 #3 #4.



My search goes on.



Thanks again. Its been a good debate.
 
a wet /dampened DF microfiber(terry type) - which is by far the best MF i have ever used for glass - used w/o chemicals of any sort to first clean the inside glass - then, followed up with a grey ww MF (one from Autopia store is great btw) with a little cleaner applied to the towel - pick any - i like the EF for it's alcohol content but i also mix my own white vinegar and water - and i assure you of the results - none of those miserable streaks that the sun angles expose-and if you are really in trouble break out the newpaper - that is a pita but never fails
 
The people from the GURU REPORTS should "REMOVE" the point / grade for product availability as it affects the final rating of the product. Even if it only accounts 10% of the final grade... it will still affect the over-all rating of the product.



Example, the #3 on the Guru Glass Report should have been the #2 in terms of "ACTUAL PRODUCT" performance but due to the point / grade for prodcut availability it was dropped to #3 ranking.



IMO, "product availability" does not in any way contribute to the

over-all performance of a product. The review should concentrate

on how the product works and leave the product searching to the consumer.





QUOTED FROM geekysteve :

"And, like I've said 1,000 times already, our reports are not intended to tell you to go out, buy something and then use it exclusively - they're comparative information on various products. "





Geeksteve,

If indeed your reports are not intended to tell us to go out, buy something and then use it... then EXCLUDE the product availability. Finding the prodcut is not your concern, it is our conern the most that you should do it state where the product

can be bought instead of rating its availability.
 
In addition,



Product Availability is subject to the User's Geographical Location.

In some cases, all the tested product might be available to one county / city / state therefore, it should equaly get an A+ grade.



Moreso, the point grade of the Guru Report for prodcut availability was not qualified at all. Meaning, we do not know from what part of the United States or the world they are basing the availability of the product.



Hope those people (Guru Reports) listen and the next time they published a report they should REMOVE the product availability point / grade factor.
