epic product

I use this all the time on so many parts. cleans with so much power and dries fast and its just everything you want and need in a cleaner.


Another great product

I bought this product for the throttle body plus other parts and it works fantastic, I would like to see a straw stick added to this because sometimes you just can't reach with that spray.

Powerful and effective

I bought this product because my throttle body was sticking at tip in and I am glad I did. A few sprays and a quick wipe removed the ridge of carbon buildup
