I have been using an Iwata HP-CS airbrush. lately the trigger (when pressing down for air) gets sticky. I think some paint may have backed up and got down into the spring. I use lube on the trigger against that other metal part and I know thats not the issue. I can't seem to figure out how to get in to look at the spring or to get it clean. Someone suggested a ultra sonic jewelry cleaner. I'm planning on calling Iwata tech support later in the week if I can't get a resolution.
I have tried some drops of airbrush cleaner down into the valve where the trigger is. That works but for a short time but sometimes longer.
Ideas??
Thanks!
Mike
