Trialling different solvents, while breaking a barrel in.

Be wary using some top end engine cleaners. GM Top End cleaner is now no longer available to the public as it is apparently carcinogenic. Andy.

Tried the carby cleaner on a nylon brush. I did not get any extra carbon out of a clean barrel, so i suspect my usual cleaning regimen is getting it all ....

I use sweets monthly and other weeks i use hoppes 9 or whatever, just to remove powder.

Me too...had to try the carby cleaner.....pleased to report that it didn't show the slightest bit of carbon.
