HP21 - What's the best way to clean it?
Hello all,
Hooray - I've managed to buy a functioning HP21 which looks a little grubby. Can I use alcohol to clean it ( I really don't want to damage it any further)? Also, what is the best way to replace those 4 (grubby?) pads the calculator rests on? Any advice greatly appreciated! Rolf PS: Once cleaned I will post some pictures |
