By solvent, I assume you mean hot H2O with a couple of drops of liquid soap?

Could get really expensive, else.

I tear mine down totally about once every six weeks or so - but then I shoot it most weekends, too. Otherwise the grips come off, the nipples come out, and it's toothbrush and barrel brush time.

BTW, put e TEENY amount of Coppaslip or similar on the nipples when replacing them, and do that by holding the cylinder in the one hand, and turning the nipples in at the same time as having a firm-but-just-slipping-grip on the cylinder. Tightening to cylinder head settings is NOT necessary.
