Many thanks to SWLing Post reader, Danny Garris (KJ4FH), for the following guest post which originally appeared on his blog, Up In This Brain:
How I cleaned the sticky coating off of my Grundig G6 radio with guidance from KJ4FH
A few weeks ago, I reached out to Danny Garris, KJ4FH, for help on getting the sticky coating off of my Eton E5 radio. I noticed on eBay that he was selling Eton radios with the gunk cleaned off and I was wondering how he did it.
Where does the sticky gunk come from? Well, for some reason the “geniuses” up at Eton/Grundig put a rubberized, chemical coating on a series of radios they released. They looked great new but over time, them coating seems to get adhesive-like properties, almost like it is melting off. It apparently has something to do with humidity and over time it makes everything stick to the radios – dust, dirt, you name it. It’s terribly annoying and just plain nasty. Shame on Eton/Grundig for doing this because a whole generation of good radios are impacted.
This leads me back to Danny and the instructions I have posted below in my Dropbox with his permission.
I used rubbing alcohol at first on my Eton E5 based on some back and forth emails I had with Danny and it did remove a ton of the gunk but I also ended up with places in the finish where the paint was removed, as he warned. Still, my concern was getting rid of the gunk more than appearances since my Eton E5 is a radio I use almost daily that I have no intention of selling. In fact, I am keeping an eye on eBay for a spare unit to purchase just in case because the E5(also Grundig G5) is an amazing radio.
Not long after getting his full instructions with oven cleaner as a new ingredient to try, I noticed a Grundig G6 for sale on eBay for just $19.99 as a buy it now price. I briefly had a G6 years ago and I have always missed it but good units are typically somewhat expensive and rare. This G6 was advertised as working perfectly but completely sticky. The seller posted pictures showing it was one of the stickiest and nastiest radios I had ever seen. But, armed with Danny’s method for cleaning the radios, I grabbed it, knowing I probably would not get another chance at a G6 for such a cheap price.
Below are before and after pictures. The before pictures are from the eBay auction and the radio did in fact arrive that nasty but it does work perfectly! In fact, it is a fantastic performer for the size. I love the tuning knob and the tuning method alone makes it much easier and more fun to use than my Tecsun radios and my recently purchased Eton Traveller III. The G6 is a worthy companion for my Eton E5 and I am very pleased with this purchase.
The after pictures are from the hour of work I did cleaning the radio last night. So far I have cleaned the radio with oven cleaner only. I took about 45 minutes using the Q-tip method and then about 15 minutes “polishing” with a clean white cloth dipped in oven cleaner as I went. I still have some additional detail cleaning to do but the results so far are like night and day.
I owe Danny a big thank you as you can see in the images below and, keep in mind, I still have a bit more work to do so this radio is going to look even better shortly!
Here is the front as shown in the auction. Gross! According to the description, the seller bought it at an estate sale.
What a difference some over cleaner makes! I need to blow out the speaker with compressed air to get the Q-tip remnants out and do some minor detail work but the front is almost in new condition now.
As shown in the auction listing, yuk!
I may do a little work with rubbing alcohol or WD-40 to get the shine back on this side but wow – what a difference!
I wonder if this radio was laying in the grass or something. It was nasty to even pick up and touch!
After oven cleaner, it’s like new again. I need to do a little more detail work but that’s it!
This picture in the auction made me wonder if I was biting off a bit more than I could chew!
I still have a bit of work to do on the back but WOW! What a difference!
What a difference, indeed! Thanks for sharing your experience and results, Danny!
I love my little Grundig G6 and, for some reason, the coating has yet to become properly sticky. I know it’s only a matter of time, though, so I’ll keep this procedure in mind.
A great portable radio is your passport to the world while traveling, even in remote areas.
I receive a lot of emails from SWLing.com readers, quite often from those who about to embark upon international travel–sometimes to remote locations–and who are looking for a durable travel shortave radio. These travelers are looking for a basic travel radio which, while it might not need to survive being submerged underwater or dropped from a cliff, will hold up in the semi-protected environment of a suitcase or backpack experiencing some rough baggage handling.
I travel a great deal myself, and always carry a shortwave radio with me (actually, I usually take more than one). Here are some considerations I use to determine which radios go in my bag or pack, and thus make good travel companions:
Rugged enough to withstand typical suitcase/backpack travel conditions
Lightweight and relatively compact size
Supplied protective travel case
Efficient operation on AA cells, the most common batteries found in the world
Useful travel features, like auto-tuning, alarm/clock functions, sleep timer
Relatively inexpensive–if you lose your radio or it gets stolen, you don’t want it to ruin your trip
To be clear, none of the radios on the list that follows are marketed as “ultra-tough radios”–indeed, I know of no capable SW portable that is–but these do represent the most durable I’ve personally tested and used in my travels.
This Sony shortwave radio is a classic, with solid, time-tested performance, and features to please both the beginner and the seasoned radio enthusiast. It is full-featured, with excellent SSB and exceptional sync detection. I grab the ‘7600GR when I plan to do a little DXing on vacation. It has everything I need.
The Sony ICF-SW7600GR is still made in Japan and the case is metal. It feels like a very high-quality portable when holding it in your hands. The lock button is a sliding switch on the top part of the radio face–easy to turn on and off intentionally, difficult to do so unintentionally. Additionally, it comes with a decent padded case. The ‘7600GR operates on 4 AA cells. The only travel feature the ‘7600GR lacks is an alarm, and that’s okay by me; for the features and durability, I’ll keep the Sony and use my cell phone or watch for an alarm. The instruction manual is comprehensive and easy to read. Read the full review here.
Actually designed with the traveler in mind, the Grundig G8 will make for an excellent companion on your next venture. I’m quite impressed with this radio: shortwave reception is good, and FM reception exceptional. The AM broadcast band does suffer from some images (a type of signal interference in which aural “ghosts” of other broadcasts layer over the one you’re trying to hear), though still quite respectable. The G8’s audio is a little tinny out of the built-in speaker, though quite good for a radio this compact. The customary price for the G8 is $49.95, but occasionally retailers place them on sale for nearly half this price. I especially like the fact that there is a front cover on the G8 which protects many of the controls. The body is somewhat rubberized and the zip case that comes with the radio is padded and perfectly designed for suitcase/backpack travel. The G8 is also smaller than a paperback book.
The G8 does not have SSB capability like the Sony does, but it is a good product for casual broadcast listener. The G8 also has a great alarm clock function and a world time selector switch on the front: simply dial up your time zone as you cross the planet. The G8 uses 3 AA cells.
The County Comm Marathon ETFR Emergency Task Force Radio is a very small ultra-portable radio. The ETFR is similar to the earlier County Comm GP-4L, but was produced initially for the Canadian military, thus it features enhanced cold-weather operation. It is very durable–indeed, military-grade durability at least with regards to impact. To my knowledge, it is not waterproof, but it will certainly withstand your airline’s roughest luggage treatment.
The ETFR is no incredible performer, but the price is low and it is quite capable of catching the major international broadcasters–indeed its sensitivity is better than I had anticipated. The tuning is actually analog, though the display is digital, thus you can expect a little receiver drift if you keep this radio on a broadcast for very long. The ETFR operates efficiently on 2 AA cells providing up to 150 hours at 40% volume or 70 hours of illumination from the built-in LED light. The ETFR also has a built-in clock and alarm feature.
In my humble opinion, all frequent travelers should keep a County Comm ETFR in their go-to vehicle and/or travel bag.
Also (I have to admit) this radio looks very cool in the carry case that Universal sells. Together, these make a great bon voyage gift for any traveler.
