Okay, so my part time job is dishwashing at a local restaurant. I hear you should avoid dishwashing as it ruins callouses... ; however, my callouses, after pullin' a shift, are actually deader and harder, letting me play more comfortably. I thought dishwashing wrecked callous progress?
Well, from what you say, apparently not.
And that's a problem?
I noticed when mine get wet they get softer while they're wet but as soon as they dry they're the same as they ever were, but I guess if it's working for you just keep up with it?
It may be the soap is drying out your skin. The problem is just wet skin. If for example you put rubbing alcohol on your hands, it'll dry the skin and make calluses form faster.
