I ordered this product alongside the Mystery box and I am very happy with it's powerful and easy application. I used about 2 ounces with 33 ounces off water in a foamer and it performed very good. Just sprayed and let dwell for few minutes it didn't dry up fast even in very hot conditions. It's safe and I used the minimal dilution ratio. Fictech Foam wheels makes cleaning wheels very easy and it's economical I am very satisfied with this product.
