Rubber coating on ST16s controller

[slw74]

Hi everyone. I have 3 ST16s controllers, one for Typhoon H Plus and two for H520s. They are all about the same age and are all stored in the same location on the shelves in the garage. All of these have a coating on the front surface that helps with grip, but the coating on one of them has become sticky. Does anyone know of a method (or cleaning agent) that would help to remove the stickiness without damaging the coating?
Thanks,
Stephen

Slow-Mo tip over after landing

Typhoon H has a couple of firmware problems than never were solved and never will because the H is discontinued. With PX4 autopilot FW the H performs very smooth landings. https://1drv.ms/u/s!Au__y3NGLbYEjiSTvzEA6pdKJGl1?e=jC9BFt The first problem is landing detection. This depends on many...

I have had this on various things, latest being headphones and my DSLR grip, I use IPA to clean them, depending on how bad might need a couple of goes, never had any problems with using IPA.

Is IPA Isopropyl alcohol?
I have the same on my Lumix DSLR and some othe things but not on ST16 (luckily).
THe effect is caused by leakage or diffusion of plasticizers from plastic or rubber parts.
Some youtuber recomment so-called orange oil cleaner. Don't know if this helps...

I have had this happen on an ST10+ and an ST16. As @Sheepdog mentioned Isopropyl alcohol will clean this. Big areas use a lint free cloth and small spaces and crevices a swab works well. For edges that a swab cannot get into tweezers with a small piece of lint free cloth works.

is IPA Isopropyl alcohol? Yes.

Well, as usual, the folks on this forum give good and useful advice. I used isopropyl alcohol initially (until I ran out) and then switched to Simple Green (which has alcohol as the primary ingredient). After about three applications, there was terrific improvement in the "stickiness" and it looks great. Thanks to everyone that forwarded good solutions.
All the best,
Stephen
