Hi Debra, Welcome to the Phorum!
If you poke around on the Phorum there are some threads discussing techniques for cleaning knobs and buttons. I use the warm water and Dawn with a toothbrush approach. If they are really grungy I'll use some GoJo (the type without pumice in it) on them as well. I'm not sure about the buttons on the 41-280 but many of those pushbuttons have degraded over time because the material they were made from was not as durable as the plastics made today. You can buy reproduction pushbuttons from the fellow at Renovated Radios. Scroll down a bit on this page http://www.renovatedradios.com/parts.html and you'll see some 1941 pushbutton reproductions.
