Well I would think that since beer bottles are thick glass, and that it is contents under pressure...and since people for decades have chilled glass bottles in buckets of icewater and sometimes even salt in the bath, that either goo gone or soaking in oxyclean would be OK...
I would probably go with the soaking and rinsing the bottle...not becasue I would be afraid of the goo gone having contact with the beer, but it leaving an oily residue with a noticieable odor, which could possibly get tranfered from the bottle to the glass by the steward pouring the bottles, and that would possible be picked up as an off aroma by the judge...
Just make sure you seriously rinse the oxy off the bottle, so no white scale is left on it...You could after rinsing also dunk it into a weak acid like starsan to neurtilize and scale on the bottle.
