HP-85 cover all yellow Message #1 Posted by Johnny Bjoern Rasmussen on 31 Mar 2010, 6:18 a.m. Hi folks My HP-85 has a very yellow cover. Can I do anything to brighten it up a little (not by painting, thank you) I'm shure that I have read about this earlier here... Cheers! Johnny

Not good to show a perfectionist... Message #5 Posted by Michael Meyer on 31 Mar 2010, 2:48 p.m., in response to message #4 by Lyuka Great... now I have to take all my Woodstocks apart and re-do the cases if I want them perfect. Anyone know, if I soak a keyboard, will it remove any of the paint finish? Some of mine have slightly yellowed keys.

I had no idea of that solution. Googled it and found this. Found out that the danish name for Hydrogen peroxide is 'Brintoverilte' and are used to teeth bleaching. I will buy some and make some experiments. Not on my teeth but on the battery lid of one of my HP-21's. Edited: 31 Mar 2010, 3:48 p.m.
