White knobs "yellowish"
« on: September 03, 2020, 10:24:58 am »
Hi!

I just got a B-Stock Microfreak from Thomann. Everything is working fine so far, but the white knobs have a nasty "yellowish" color on the edge (like being washed out or something). As far as I've seen in online pictures, normally those are pristine white.

Is that normal? There's any way to polish It (dismount the knobs), or buy new knobs? Already tried with 75% alcohol, with no results.

My KeyStep was like that. I stuck them in a mix of 50% bleach over night. Fixed the problem. Small disclaimer that as usual you do that at your own risk etc, in this litigious society we now live in.

Thanks for the answer  :) No lawsuit problem here, don't worry..

I already read that about bleach, but I was unsure about how to remove the knobs. Since these are not regular "turn" knobs, but also "click" knobs.

Anyone have any experience removing the knobs?

Again if they're the same as the Keytep they're just a push fit.
