Or you can visit Ginnie or Little River and let the pressurized fresh spring water clean your gear.
I agree, a local fresh dive clears all that crap right up
I was told to fill the bathtub with warm water, soak for an hr, drain and do again for an hr (honestly after the second soak I forget and deal with it later). Dust caps on for the soak and then once home leave the dust caps off for a ~ week and let the internals really dry out.
Works for me, and no worries about any solutions taking the finish off the regs.
