Which is the best Auto Glass Cleaner?
Good question.
I am in the middle of an Auto Glass Cleaner research project with the intent on finding out the answer to that question.
You also have to decide what factors matter most to you.
- Cleaning ability.
- Clarity.
- Deep Clarity.
- Reflection.
- Shine.
- Scent.
- Surface Cleaning or strictly Auto Glass.
- Eco friendly or not.
- Price point per ounce.
- Specific vehicle type and intended use.
- Hydrophobic
- Showroom presentation, Museum presentation, Daily Driver, etc....
- Application (Yes, it matters. Some Auto Glass cleaners take forever to buff in to achieve the baseline performance offered by the product).
To be honest, if I were you I'd try the Armor All glass cleaner out of those 3 choices. Reason being is I've heard surprisingly great reviews of it from reliable sources who know what they're talking about. [i.e. Darren from Auto Fetish]
Plus it can be easily found at just about any auto parts store etc.
I will offer some brief thoughts on the products listed n the OP.
I will have a more in depth write up later on, but for now will post a few very brief thoughts.
The first product tested, and actually first tried this product around 10 years ago, is Armor All Auto Glass Cleaner.
This product excels in every category listed above.
It is to date the best Auto Glass Cleaner I have ever used.
It also has many crossover application.
I use it to clean industrial equipment, power tools, all kinds of machines, office furniture, and everything else.
I could not be happier with this product.
I was the one who actually recommended this product to Darren Priest of Auto Fetish.
Meguiars Perfect Clarity.
Fantastic Auto Glass Cleaner.
Classic Meguiars scent.
Ceans glass very well.
Very nice clarity.
Showroom reflection and shine.
Rain X.
This product is the second worst Auto Glass Cleaner I have ever used to date.
I honestly never thought I would find a worse auto glass cleaner until I continued testing using another product recently and found one.
This product fails in every category listed above.
Avoid this product.
Rain-X 2 in 1.
This product is miles better than its sister product listed above.
It is a leaps and bounds improvement and excels in every way by comparison, except for one thing.
The final result.
This product has a serious problem retaining moisture and residue.
I used this on two separate work trucks, both had the exact same problems.
The moisture of the morning dew would just not go away.
It also rained latter in the day and the retained moisture created by the rain drops left a smear and foggy windshield that would just not go away.
In order to simply be able to drive and see out of the windshield I was forced to remove all Rain X from the windshield.
That took some serious work to clean and buff it all away.
Not only is this product one to avoid, I would list it as a safety hazard and issue a warning regarding using it.
Hope this helps.
