The soft feel coating used on a variety of plastic products AKA TPE coating, which can sometimes break down into a sticky gunk, which attracts detritus and is unpleasant to use, and difficult to rectify.
Many people have reported problems with it here on the forum, whilst others have not had issues.
Some examples of products which have this coating:
Elektron MK2 and Digi products on the buttons.
Ableton Push on the body.
Akai MPC Live on the body
AIAIAI TM1 headphones on the ear cups and band.
Moog Little Phatty Stage on wheels and sides.
There are other methods of plastic finish which do not go sticky such as mechanical abrasion which can give a matte finish, this is not to be confused with TPE coating which has a rubber like texture.
Arturiaās Beatstep pro encoders as well as the whole side cheeks and knobs of the Minibrute work perfectly as fly catchers after some years degrading to rubber sticky glue by unwanted synthesis. Managed to rub the grease off with covid alcohol hand cleanser.
Mutable instruments eurorack modules have rubber feel knobs too but they donāt seem to dissolve in post-it feel.
Yeah, I cleaned the normal beatstep, the knobs feel much better without the coating although the encoders are fairly useless anyway due to their scaling.
Also had to do a KM Qunexus, which looks terrible now & a Corsair M65 Pro which feels better without. I also had a Push mk1 for a bit & got rid of it when the coating was just starting to come off.
I used to like it until I dug out my Push 2 that had been sitting in a travel bag for a while and it was gunky as hell. At first I thought I must have spilled something on it so made the mistake of wiping. And wiping. And wiping. And wiā¦. You get the picture. Still a mess.
If a Push 3 appears then I hope they ditch this plastic shite.
My MPC live is unsellable, not that I want to sell. But gross to use. Especially being a neat freak, there is no cleaning it. Trying to clean it actually makes it worse. If I ever wanted to upgrade to a newer MPC, should there be oneā¦I could never sell this sticky mess to anyone. And I shame to just throw away.
