Question about Nikon Stay Focus Plus II 7878 (8x40) Binocular

Open Question

My nikon sprint II binoculars have a sticky feeling on the outside rubber coating so when you hold them in your hands, every place you touch is sticky. I've tried wiping them off, but it seems the rubberized surface has become permanently sticky. It doesn't leave a residue on my hands that I can see, but I just wonder. What a crappy product. Is it covered under a recall? I don't remember when I bought them, but with a name like Nikon, it shouldn't be like that.

    I cleaned off the sticky rubber coating with rubbing alcohol; the surface was actually removed. The surface left behind is hard plastic, foggy looking, but a good rubdown with a clean cloth left it looking shinier than the original surface. I guess something like ArmorAll would perk it up. Note: All printing and graphics on the surface came off. I was also very careful around the lenses; don't know what alcohol or vigorous rubbing might do to iridium coatings, etc.

The outside of My unit has become sticky and has an odd aroma. I think the chemical component coating is changing. I have included a picture Ser# CE0389 Respectfully, ken henson


Try applying the solution for sticky old Tupperware . Rub with a rag or paper towel moistened with household ammonia until the sticky surface is no longer sticky. Worked like a charm on my sticky Bushnell binoculars (and on Tupperware). .They were unusable before treatment. I suspect plasticizer migration.

Rubber coating has become sticky


try keeping it in a cooler place and the rubber should harden
however I would first check the box to see if it is supposed to be tacky which means it is supposed to be that way

Do you mean the Swift Audubon 8.5x44? If so, for the new model 820 contact Swift Sports Optics. If it's the older model 804 ask around in the forums such as Cloudy Nights. The new model 820 is rubber coated. The old models have a grey crinkle finish.

My Chinon 10x25R binoculars have the same problem.


Simple use soft lint free cloth like old drying up cloth, you need about half a cup of methalayted spirits,can get this from any hardware store.
poke finger into cloth dip into meths proceed to rub sticky coating off binoculars. you will need to keep changing to a new peace of the cloth as soon as it gets coated with the sticky black stuff off binoculars.
keep dipping into meths eventually after say 6 rubs in a particular area you will see and feel a nice hard black plastic, continue all over effected area then finish off with any window cleaner polish until cloth remains clean.STICKY COATING IS NOW GONE IT WAS INFACT A COATING PUT ON THE BINOCULARS TO MAKE THEM NONE SLIP. job done. regards GER8

Case is "sticky" like glue


The same thing happened with my old Praktica Sport Zoom binoculars, and (in my case) found that the sticky coating could be removed by repeated rubbing with paper towels moistened with methylated spirit ("meths"). SAFETY FIRST: If you decide to try this method and have not used meths before, it is a very flammable liquid, and harmful by touch and inhalation, so please wear rubber gloves and do this outdoors or in a well ventilated place and away from sources of heat or fire. That said, it is cheap and readily available from DIY stores, usually in their painting section.

I have the same problem with my Nikon N65 film SLR and I bought a vintage Super 8 movie camera where the rubber had turned to the consistency of gum on a side-walk on a hot summer day. On the a camera I carefully rubbed on a coat of talcum (which probably isn't the best thing to use on a camera but I was careful and it isn't something I do every day). I then took a small square I cut from an old terry towel and used friction and elbow grease to rub off the top layer of the rubber. I then took another square of the towel and dipped it in hot soapy water, squeezed out the excess and washed all that remained. I then took a small water-colour brushed (after I dried the surface of course), and dusted the surface of the rubber with talcum and let it sit overnight. This seemed to stop the derioration and clear off what had built up. The next day I took a very dry damp towell (if that makes sense) and wiped off the surface. It pretty much took care of that problem. That was the Nikon, it was only in the beginning stages, the Super 8 camera which had apparently hadn't been out of the case in 20 years. The Super 8 was so bad that I don't even know what had deteriorated, probably a rubber eye piece, that one was time consuming but basically I put the powder on carefully and just wiped big clumps off the metal eye piece. The powder just served to make it easy to clean up and kept it from turning into a 3 stooges farce with one thing sticking to the other and so on. Well, I hope this helps, I don't know why it works, maybe there's a chemist out there that can explain it to me. Good luck!!

Rubber coating breaking down


Try it with rubbing alcohol first - just keep it away from the optics, and you may get lucky. The only thing that ever seems to work with these is an abrasive cream cleaner (jif/cif or similar) - you just have to use lots of cream and be careful not to polish the optics - unfortunately the stickiness will come back quicker than before though. I haven't tried myself, but i have heard that once you have carried out the cream cleaner routine, you can paint the unit - ask your hardware shop what sort of rubbery paints they have - ideally oil based and not acrylic. It wont last as long as the original finish or like quite as good, but it should stop the stickiness for a while at least. Try and keep your binoculars out of the sun - most of the stickiness is either caused by that, or contact with a damaging chemical such as most insect repellents, or petroleum products. Hope this helps :)
