Due to the many positive reviews and the reasonable price, I ordered the hat-trick. I'm really very happy with this grill cleaner. The foam remains surprisingly long time and even after a night was still "residual foam" in the oven and on the baking sheet. The cleaning performance is also convinced. Since I also use for quite some time oven spray instead cleaner, I've tried this spray also with my wheels. The foam also keeps here much longer than the oven sprays previously purchased by me from the supermarkets and also comes in every corner. The foam can then be just waving in the worst places wipe with a sponge, otherwise sufficient with water and the rims are again perfect! Try it out: Cheaper and better than any advertised commercially wheel cleaner!
