Many shortwave radios, such as those manufactured by Grundig/Eton, have been produced with a rubberized coating that makes the radio easier to hold in the hand. I like this coating because it gives me a sure grip on the radio.

However, over time (say, two to three years) the coating can break down and begin to produce a sticky residue. All of a sudden your “grippy” coating feels more like tacky paint–even leaving a bit of residue on anything it touches.

Many models have this coating: The Grudig G5 and G3, The Eton E1, E1-XM, FR350, FR400, FR500 and FR600, to name a few.

Michael Kitchen (KD5PXH) recently wrote with his solution for sticky radios:

After experementing with cotton balls/pads, and using window cleaner and other liquid agents, I managed to decently remove the gummy coating from an Eton FR-400.

Best to use 91% Isopropyl Alcohol, and a clean but disposable (dry) wash cloth or something similar.

The stronger percentage alcohol makes for easier breaking down of the sticky, and the wash cloth to remove, without damaging the surface or removing lettering. The trick is to always use clean spot on wash cloth, keep from just smearing the stickyness around. The wash cloth will lift and absorb sticky, so keep using a clean spot on cloth. The cloth needs only be damp with alcohol, not dripping wet. Use dry spot on cloth to wipe clean the surface.

There may be a hazy white patina, but much of this can be wiped away.

It takes a little bit of effort, but the results are worth while.

Thank, Mike!
