I thought back flushing was not a recommended practice because of the potential to push paint and cleaner into the back end of the brush.
Yup. Regardless of whether I've back flushed or not, there still seems to be that little bit of paint dried inside on the needle. Now, if you've got PTFE seals for the needle, they will wear with movement of the needle from the dried paint and you end up with a not perfect seal on the needle. I find my Infinity is particularly susceptible to this.Might take a look at this later. No matter how thoroughly I think I've cleaned it, if I don't use it again within a few days the needle is stuck....

I think back flush doesn’t necessary for cleaning. I alway use interdental brish.
That's another good habit I think people don't consider. It may be a bit of a pain to do on an Iwata with the screw-in nozzle, but it's the best way to remove the needle.When this happens to me, I always remove the needle from the front. Dragging it through the seal will damage the seal. That is also why I like the Eclipse and the Micron.You can clear the front without tools.

So it's bad to remove it from the back and also bad to remove it from the front and bad to back flush it. ???
back flush not bad but it’s unnecessarySo it's bad to remove it from the back and also bad to remove it from the front and bad to back flush it. ???
