## Questions & Answers

**Q: How do you use the cleaner**
A: The cleaner is put into the gas tank. My catalytic converter was reading below the threshold level which caused a dashboard light to go on. I used this cleaner and the light did go out but eventually came on again. The light stays on for a few days then goes out for a few, so I would have to say problem not solved.

**Q: did YOU clear your code/checkengine light after you used this product? or did the actual product clear the code itself?**
A: I treated back-to-back 2 tanks of gas  - 1 bottle per tank - and it cleared the check engine light after aprox. 1,000 miles, a trip from Nashville to Picayune, and back...  I didnt have to manually reset the light

**Q: Will this help clean the catylic converter and help get rid of egg smell**
A: It helped my car a lot ,I plan to use it againThe egg smell is almost gone. Some car you just replace the CAT but my car it's the hole thing so you might want to call a muffler shop for price first.my friend got his done for 50 installed mine was 275 installed

**Q: Can i mix this with gas treament ??**
A: Yes it can be mixed with a tank of gasoline.

## Customer Reviews

### ⭐⭐⭐⭐⭐ It actually worked....Go Figure...
*by J***A on October 31, 2016*

This was a shot in the dark, but for $12 why not!About a month ago my CEL was popping on and off intermittently. I had a code reader already I had not one, but two P0420 codes--and one of them was permanent! I immediately thought it was my cat converter going bad, specifically because of the permanent code. I did the visual checks and nothing appeared melted or out of sort, so I began to do all the research I could.I tested the temperature and also the O2 sensors and they checked out. I began to get even more nervous that it was in fact the cat going bad. I was looking for a legit way to clean the converter without having to take it off. People had suggested lacquer thinner, but that didnt seem to work for anyone that had actually ran it through their fuel system. So, I started looking online and this was the only product that had positive reviews beyond belief to actually clean the cat system. Low and behold.....200 miles later, and no more CEL, it also cleared my permanent code! :Ohow i did it:Ran my car down to less than a 1/4 of a tank of gas.Poured 1 can of Catalytic Converter Cleaner & Deodorizer into the gas tank. (funnel recommended :) )Ran that 1 tank of gas to about 20 miles left ~.Reset CELFilled my car back up to a 1/4 tank of gas.Burned that offRefueled to fullHooked up obd2 reader once more to see if P0420 codes were existent at all...Nope, Permanent wasn't even there anymore.Fuel efficiency is actually up a few mpg. went from 25 to 27 mpg and also my car is noticeably more silent when punching the gas.I've been driving for about a week now and it has not popped back up yet. If you feel like your cat is dirty or dont want to shell out money for a new O2 or even a new cat, I would definitely say this is worth the $12.

### ⭐⭐⭐⭐⭐ Mario
*by M***  on April 3, 2025*

I dumped the whole bottle with a full tank and gasoline

### ⭐⭐⭐⭐ Worked in combination with Cataclean to keep code clear.
*by B***N on December 6, 2019*

So I had the P0430 code on 2005 Cadillac STS, which true dual exhaust meaning there are two catalytic converters and just the cost of those along would be well over $1000 before installation. Figured I would try Solder it as well as Cataclean together to see what happens. On almost full tank, I poured entire bottle of Solder it into the tank and drove as normal until reaching just under 1/4 tank at which point, per instructions on Cataclean, I put in bottle of that and drove per instructions before filling tank and continuing to drive as normal. For first 3 days, car kept throwing the same P0430 code and I kept clearing it out. On day 4, I drove into work and just out curiosity, I attempted to use my remote starter (this function will not work if there is a code stored in computer) and it started right up, meaning, there was no code. Usually the code would appear within minutes of clearing it if I started the car or drove it at all. So, these two products together, have at least had some improvement in clearing the P0430 code I was receiving. Long term, not sure at this point. But, I will most likely run the same two products again in a month or two and see what happens again.I will update with any new information. But as for now, I would rate this at 4 stars since it did what it was intended to do and I have definitely observed less of an odor from my exhaust.
