CRC Clean-R-Carb Carburetor Cleaner (50 State Formula), 12 Wt Oz, 05379

It is too powerful, it can eat rubber, I used it on OEM durty bad performance idle air control valve, and it performing now like new one, but it destroyed the IACV gasket rubber,luckily I have old used one I used it till new one arrives. If you want to clean throttle bodyake to remove it and do not spray sensors, only inside durty black gum, and if you want to clean IACV, make sure remove gasket or have new ready Incase of old one destroyed and spray inside the valve and after and let it soak for just 10 to 15 second and then install it back and run your car immediately, the vacuum will remove the solution and in the meantime will clean the valve, and repeat again if you notice improvement, but not enought, of course you will have better.working result if your IACV is not defective electronically. If no improvement happen after three times then replace the whole IACV.

Used it to clean out all the lines, clean the carb, then prime the spark plug. My little 50 which hadn’t been started in 3 years cranked right over. Good stuff.

not a lot of success with it I used it I had to end up taking the curb apart from my lawn mower really wasn't a lot in there the carburetor cleaners should be able to handle it but it did not

CRC make some of the best cleaning solutions. I was about to do a timing belt replacement and needed something that would leave the timing belt bay spotless. I got this stuff as I had gone through two cans already and my local store didn't have any. I dearly recommend to DIYers who want to save time and money.

Bought as a gift, he uses it frequently so I am sure it delivers adequetly.
