98, I didn't take what SS said as a jab at you, or what you do. Most gunsmiths will clean guns for customers....easy cash for them when they don't have better things to do. I learned a lot from a deceased gunsmith that loved hunting season.....he would make BANK by cleaning the solidified WD40 out of the idiots shotguns for them. And they were happy to have him do it,may for it, sit in the bar a block down the street, and redo the whole thing every year.
If you have set yourself up to not do cleaning for customers, cool beans. Good call on your part. Some may not have the customer population available to make such a move.....that was part of my friends' necessity to do cleanings....for the leaner times of the year.
And as an aside, I actually tell my local bike dealer to not waste their time on cleaning my bike for me when in for some service work. If you ride them, they just get dirty again. And, if it is THAT dirty, I will clean for the tech.....
