Good morning, everyone:
A couple of years ago, I asked about removing the carbon coat from the interior of a bell jar, specifically regarding a Denton vacc system. We recently purchased a JEOL IB-29510VET turbo-pump coater and I was faced with the same issue. Last time, several of you suggested using hair spray, which does work quite well - I have found that VO5 spray works very well. Also, I have had good success with Micro-90 concentrated cleaning solution. I apply a very thin coat to the region to be cleaned and wait a few minutes for the Micro 90 to give the coating a wrinkled appearance, and then simply wipe off the residue followed by a rinse using water and then ethanol on large kimwipes to remove any remaining Micro 90 or carbon. Hopefully someone else will find this useful. Happy New Year!!
