Solder-It (CAT-1) Catalytic Converter Cleaner - 16 oz.

After using another engine cleaner, the engine light came on. I expected this due to the catalytic converter sensor being flooded with crap from the first cleaning. I used this to clean the CC and the light went off!

can not rate the product yet but used before and worked super TAKE NOTE UPDATE GOT RID OF CHECK ENGINE LIGHT AN PASSED IN FLYING COLOURS THE E TEST UPDATE FEB 16/15 THE BEST U CAN BUY B U T ITS A LOT CHEAPER IN STORES

Works very well highly commend it

Cleared the check engine light after one tank of gas. Excellent result.

I bought this to clean the O2 sensors to avoid replacing them to no avail. The failure code came back up with 25 miles and continues. probably cleaned injectors…
