Just like any other Poorboy's World products this can be used in direct sunlight, which is a plus for using on a hot windshield or exterior glass. Can also be used on interior glass as well. It has a slight lemony/citrus scent. This comes with a very nice sprayer which is a plus. I just wish it came in the 32oz Refill. But other than that, it's a great all around glass cleaner with a refreshing scent, and streak-free one wipe and done!

I have used numerous glass cleaners in the past. I kept telling myself there was nothing better than ‘Invisible-glass’. This Poorboys Glass Cleaner is on another level. It sprays on like a mist and stays on the glass, hardly ever does it run down. One could use any towel to wipe it off and the results are clear! What did it for me, is using on direct sunlight in humid weather and still doing its job.

Works like glass cleaners I have paid a lot more for but did so on hot glass in direct sun. Very nice.

Works great! Used with a waffle weave and had perfect results.

The key to this glass cleaners success is that it lets the microfiber towel glide over the glass instead of grab like microfibers do with any type of powerful glass cleaner, the same way it would on your paint With no wax or sealant and you were drying the paint after a wash with no drying aid, spray wax, or detailer. You are also less likely to have linting from your towels with this type of cleaner. Does a great job of cleaning dirty glass, no streaking, smells fantastic and just plain works. I also tried it cut 50% with distilled water and it still had good lubricating properties and cleaned the same although I never really let my windows get that bad. A comparable product would be pinnacle crystal clear glass cleaner with water repellent that I have also used and it works just as well.
