i tkae all the componets like the firering pine and the spring ect. and soak them in hot water and spray alittle of wd40 in there and let it sit over night then wipe with the brush and rub with some patches and it looks good as new. There is alot of ways i have tried but this one seem to work for me. I have a black Diamon and an Omega and it seems to work fine with both guns. The only disatvantage is that you use alot of wd40.

Goodluck, bowhunter818
