Okay, the number 30 sunblock will remove fouling in your barrel if followed by a brass brush and oil.

The number 15 stuff does not remove the fouling in smaller barrels like 22 and 25 Cal. but appears to work on larger bores like 338 and 375.

So, we have a new use for sunblock: paint stripper and rifle cleaning agent.

Darn, someone remember to call Martha Stewart... when she gets out.
