just got myself new ML and everything in car is like new except got steering wheel buttons that are sticky. I dono wht MB uses that antibacterial coating that always gets sticky and scratched. Anyway did little re-manufacturing and here there the results This time was lucky but if things would go wrong i have fiber laser so i can always re-coat the button graphics

So what did you use to remove the sticky coating?

answer is "i have no idea" its 3M solution that we use to dissolve 3D printer support material that smells lice citrus. GooGone is same type of solution but less strong so would take more time. I had to soak the towel in hat solution and get rubber soft. Once its softened started rubbing it with synthetic towel. More its exposed to chemical the easier to remove. I did mess up a bit by trying to use alcohol ( dont do that!!!! alcohol dissolves paint and causes scratches to it) If paint gets removed you see white semy trancelucent plastic. If you see that then you screwed in my case i made small dint with alcohol but i touch up with black marker. Technically best to do clear coat over theis but i suck with paint so i left those alone.

Another thing if you see white, its not end of the world, you can clean whole thing to white and then spay black and find some one like us who has fiber or galvo based co2 laser. Those machines can mark back original artwork so buttons can be re-manufactured easily. I was doing remarking for a friend on Porsche (not really commercially feasible projects but at least we can get car look totally new

Another option after cleaning is to use decals. Unfortunately for me, only available in black.

I find those decals look terrible, that's what my friend tried to use on Porsche and in reality look crappy even on eBay photo you can see texture under + dome one slides off all the time. Dono about you but i like my cars to be perfectly clean

Looks great! How did you do it?
That's a really common issue.

1. remove airbag (2 screws behind steering wheel)
2. remove tiptronics buttons
3. from behind of tiptroncs there screws holding main button assembly
4. remove buttons
5. take button assembly part
6. clean everything

for cleaning as mentioned before i used 3d printer support solvent (light gum cutter) same as GooGone which is almost the same. Soack towel in it, spray chemical over parts let is sit for like 30 min and then start rubbing with cotton towel till its clen. Note paper towel may damage pain. Note 2: buttons frame is black ABS start with thta its not fragile. Buttons are ABS-PC white painted with black paint, paint is fragile so going to crazy may damage paint and then buttons need to be lasered again.

If some one has extra buttons i can do a tutorial
