Hello PA.Sodas, I see you have some good results! It takes me several cleanings with bottles that stained. I usually have to add play sand to my compound to make it more aggressive. If you have any questions? Please PM me and I will Call you . Good luck!! Kevin....
I added a tablespoon of playsand to the mix and achieved slightly better results on the interior however the exterior is a different story. I was intrigued enough to start working with some better bottles. I apologize I'm doing all my work in the basement and garage neither of which have windows that are photo friendly . . .
Hello Jeff, Your bottles look great, Looks like you are figuring it out. It took me several bottles and a lot of experimenting with different products. This does not work 100% for every bottle, But it works on most bottles that I have. Keep playing around with different things and share results with me if you find a better idea. Thanks, Kevin..
