Unfortunately, I have some bad news regarding cleaning with my P2.
Friday night I decided it was time to clean the P2 for the first time. I'll be honest, I had run 10 ovens through the device. Usually I'd clean my P1 after 3-4, because the MP would start to stick. I took it further with the P2 because there's no moving parts, and it has been mentioned in this thread that you can wait longer before cleaning.
I have the screen without the feet... and it was IMPOSSIBLE to get the screen out. I dipped one of the included pipe cleaners into the included 70% iso and pushed through. Well, the pipe cleaner came out of the oven.. but the screen didn't!
Upon closer inspection (I can probably post some pics tonight if I figure out how...) I noticed that the air path of the P2 is far closer to the side of the oven (nearly touching it) so that my pipe cleaner just pushed through the scallop on the short side of the screen. I actually had to remove the screen with pliers at this point, because my fingers are too big for the oven, and it was now bent from the pipe cleaner moving under it.
My P2 was NOT very dirty, and in fact, had no build-up at all in the oven, with the exception of a small amount of resin on the underside of the screen, opposite the side of the draw tube. The screen was too tight-fitting and I believe that was the issue for me. The small amount of resin seemed to seal the screen to the top of the oven so it wouldn't come out. So for now, I'm stuck without a working P2, as I have no screen! I've tried to straighten it out but the screen is pretty hacked up and will not seat back in the oven.
I'm still a bit disappointed that we were not told of different screens being sent out. The screen with feet would have worked significantly better in this case, as it would have not allowed the screen to fuse via small amounts of resin to the oven top. Then I could have pushed it right out.
I will send
@Ojan_at_PAX a message and get back to ya'll, but seeing as there are no listings on PAX Labs' website for replacement screens, I have no way to use my P2 for now! I'll try cutting a P1 screen and report back.
