It is great stuff! I mixed mine at a 2 water to 1 Robo Bubble ratio in a separate spray bottle and that was more than enough to clean my interior. Since my car is brand new, there were no tough/stubborn spots to deal with, but I have no doubt that Robo bubble at full strength would make them disappear.
I also appreciate the wonderful thank you note from Karen on the packing slip! :-)
High quality shirt and the printing is impeccable! Thank you very much
Haven't used the iron and rust remover yet, but the BS grease remover worked great on the inside greasy bits of one of my BBQ grills. Well work with again on another grill this week. Grease was so heavy that it took 2 times to get it all which wasn't unexpected.
