"Self-explanatory", ...er, ...maybe, Tom...
...But (I think) a really important question, given the amount of gaffer, electrical and (worst of all) masking tape "gunk" I've had the misfortune to find encrusting bits of valuable gear that have been handed to me over the decades.
Now, you Northern Hemisphere types may need to allow for some Down Under hype in this solution to an enquiry that happened to originate on (of all days) Australia Day...
...It remains an indisputable fact that nearly all of the most severe problems that beset our planet can be solved using items (separately or in combination) from the following kit:
- Fencing wire,
- Beer cartons,
- Electrical tape ...and... (drum roll, please)
- Eucalyptus Oil.
Item 5, "Eucalyptus Oil" applies (and will need to be applied) here.
...is there a "Safest Way" to go about this?
It's really great that you've already anticipated the possible dangers inherent in any liquid (maybe especially one that's a solvent) being accidentally introduced to various internal components.
For the doubters out there, bitter experience has taught me that those dangers are all too real.
So, here's the method I've employed successfully over several decades:
- Pick off as much "gunk" as we can using our fingers.
- Form the collection of such "picked-off tackiness" into a ball.
- Roll that ball over the remaining "gunk" for it to "grab" yet more. Sadly, some will (nearly always) remain.
- Dip a "bud-type" applicator into a jar of Eucalyptus Oil B.P..
- Roll and squeeze the applicator's wet tip against the jar to remove any excess oil that may drip.
- Work that oil-moistened tip into the "gunk", which will immediately turn soft and greasy.
- Use the "dry end" of that (or another) applicator to "mop off" the now greasy "goo".
- Repeat that process using as many applicators as it takes to eventually yield clean, dry and "tack free" surfaces.
Having experimented with several strippers and solvents over many years now, I've honestly found that Eucalyptus Oil BP is not only the most effective for removing all types of adhesive residue, but also by far the least likely to mar the wide range of surfaces we regularly encounter, be they painted or coated, synthetic or natural.
Besides, ...it's been a very long while since I last encountered a sticky Koala.
Incidentally, my solution for battery door, belt clip and protection issues is to scissor-cut pairs of holes (one for antenna and one for input cable) into the bottoms of these cheap little beauties http://www.amazon.co.../dp/B00012FVY2/.
Not only does LowePro's tiny Rezo 10 fit a variety of beltpacks (especially TBP12s) perfectly and solve all of those problems, but it also enables really quick and secure mounting to both instrument straps and belts, with instant access to all switchgear.
