lubricant

The central adjustment on my Minolta binoculars were exposed to apple juice that locked the adjustment in place. I freed it up with some isopropyl alcohol, but it is still hard to adjust with one finger. Is there a lubricant that should be applied? Thanks.

Hi

Not that I can safely recommend. Do-it-yourself servicing on any bino is usually a bad idea. If the lubricant seeps into the wrong mechanism you have a return the bino to get it repaired situation, since you cannot work on one, yourself. If it was my bincular, I would simply give the focusing knob a good workout until things loosen up a bit more. If you must try lubricant, get some all temp stuff like Triflow from a bike store, but be aware that such a move will normally void a warranty. Hate to say it, but it's your decision to try it.
