I love Otis and I don't care who knows it, but all the bottles in their kits like to leak so I use these other chemicals.
Outers Foul Out electrochemical bore cleaner can't be beat for copper and lead.
KG12 if you must scrub is great on copper.
KG1 for carbon fouling works fast, although most carbon cleaners if allowed to soak for awhile work fine, Breakfree CLP is great because when you're done cleaning you don't have to reach for another bottle of oil.
Just my 2 cents.
