How to clean HP-71b keys
Message #1 Posted by Alain Robillard on 11 Mar 2006, 2:47 p.m.
Hello all,
while doing some work on my HP-71b, I drop orange juice on some of the keys. Since then, they have that sticky feeling that is very much annoying. Is there any good way clean the key contact or mechanism without opening the calculator.
Thanks for your suggestions.
