Default Cleaning a Muffler?

I know that, which is one of the reasons why I am switching to YS 20/20. All synthetic 20% oil with 20% nitro.

The 15% was about half a gallon that I needed to finish up. Looking back on it, maybe I should have just used it in my planes.

Thanks for the tip on the cleaner. Is this the correct name 'automativew wheel polish'?
