Cleaning/dielectric grease on heated bed contacts?
I recently built my first Mk3, and while assembling I noticed that there seemed to be some discoloration on the electrical contacts of the heated bed (my bed is the non-soldered version) This could be surface corrosion or some anti-corrosion coating--I'm really not sure.
Now that I'm building a LACK enclosure for my printer, I need to re-angle the electrical contacts on the bed (going with the 60-degree cover on Thingiverse), and I'm wondering if I should thoroughly clean those contacts and apply some dielectric grease while I'm at it. Does anyone know if this is a good or bad idea? And, if I should, how would you recommend I clean the contacts? My usual go-to is isopropyl alcohol, but that's more ideal for circuit boards than these kinds of higher-wattage contacts.
Thanks!
