Interior glass cleaning

[The Guz]

I have (and have tried) them all. I use Stoner's around the house about as much as I use good ole Windex with Ammonia-D , whichever I reach for first in the cabinet. I stopped using IG on auto glass a few years ago when I got my gallon of D120, and I use glass-specific MFs (waffle-weave or rib-knit). I recently got a GlassMaster Pro kit, but have also tried the CarPro FastGlass towels with plain water. They work brilliantly!

D120 is great. I am now using this as well.

Those CarPro glass towels are incredible. Saves me so much time, no streaking at all. One of my favorite detailing products

I have used quite a bit of glass cleaners but stoners is now my go to. I have yet to see it leave streaks

NEVER use rainx or similar on interiors!! They will massively increase fogging and you have insufficient access, so they can be a serious problem to remove once you spot the mistake!

Been using Stoner's for about 15 years, the best I've found for interior glass, especially the windshield.

I will add, Meguiar's "Perfect Clarity Glass Cleaner" is also pretty good for interior...but still favor Stoner's for the windshield interior.

Denatured alcohol diluted with distilled water. High cleaning power and streak free results. You asked what the cheapest glass cleaner is, this is probably it. With that being said I use Meg's glass cleaner for my business. It's equally inexpensive and smells great.

The cheapest would be distilled water and a glass towel....

Tap water. No joke, my water's not metered. I used hot tap water with the CarPro FastGlass towel and it is easily the most effective thing I've used on neglected interior glass. Streak-free, spot-free. And easier than any chemical I've tried. Stoners and D120 are great, this is better.

I use Meguiars Wash & Wax. It's streak free and also works well on the dash and all other interior plastic parts that are in good shape.
