Take this with a grain of salt......Because cleaning guns ain't that high on my "like to do list".
The sooner you run water or whatever cleaner required through gun,the better after spraying....seems like a duh statement but its priority one.We use scotchbrite on gravity feed cups interior,rightly or wrongly(minute scratches) when using water based,immediatly after using......keep dumpin out from top,quickly...refill,dump repeat.Trying to get resevoir clean as possible,quickly...then spray some more through gun.
Hold a rag over biz end at this point and percolate water back through gun......look in cup,see any colour?Dump,refill...and percolate again....look in cup,repeat.
So being in a major hurry here 'cause I've got other things to do,at this point if theres no colour showing up anywhere,wipe interior exterior with clean lintfree cloth and put 3-4 Tbs. of water(or whatever reducer) in cup and hang it up.
If I'm going to be using it in the next day or so..........can tell by just picking it up,and pullin the trigger(no-air)and watching the resultant stream of fluid comin out as to how clean it is.This won't work for siphon's.......and it takes awhile to get used to that particular guns cleaning regiment,and just what the,no air stream looks like.
I don't do complete teardowns any more than absolutly required.Now you know one of the BIG differences between cheap no-name guns and a $$$ rig.Its not only the finish they are capable of but...the better the gun,the better it holds up during routine maint.BW
Those who say it cannot be done shouldn't interrupt the people doing it.
