Hey guys. Have you guys had any problems where the tubes (Mahri tubes, the thing Stormer 2.0 has, and stuff) get really sticky/oily/wet? Because, for some reason, my current ones seem a bit sticky, and whenever I touch them there's a very weird feeling. So, do you guys have this problem, and is there any "Cure"?Also, I've washed the tubes once AFTER I found them sticky and icky. They got slightly better, but their still icky.
