## 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.

### ⭐⭐⭐⭐ 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.
