    I have the same problem My binoculars are the Jason Model 296, Perma Focus 1000. The rubber grips on top of the binoculars are super sticky and black comes off in your hand. Any solutions?

    My Bushnell binoculars, got them out last night to look at Saturn and Venus... same problem. The black rubber has become sticky over the years, and that black stuff gets on your hands and it's hard to get off. I had a pair of black boots that this same thing happened to, on the insides. Ruined my purple socks, LOL. It must be a certain type of rubber that this happens to?

    I have a sharper image 8x28 variable binocular compact that was very gooey from use and storage over the years. I can give a definite thumbs up to use Murthy's oil soap. Use full strength, place some on rag and wipe body and other surfaces till the black material is completely removed. IT may take 20 minutes with good rubbing to get it all off ( change rags or areas to minimize time). Works on rubber eye protectors also. Once you have removed the blackish material (white rag v good to see) taking another clean rag, to verify you got must off the unit then take a clean moist rag, rub the oil soap off ( should take no time at all then dry. My binoculars, though now missing most of printing and logos, feel smooth, no stickiness and works perfectly. A little soap save me better than 60 bucks for a new pair.
    Just to cover bases, I tried isopropyl alcohol, acetone and simple green and NONE of them work even marginally. The solvents made it worse so save time and get the Murthy's. PS. I don't work for them nor never have. Just used original comment suggestion!

    I bought a pair of these at a flea market, and had the same problem, with sticky goo completely covering the portion of the binoculars which houses the mirrors and prisms. i tried about 6 different solvents, including acetone (or fingernail polish remover) and what worked best of all was isopropyl alcohol. I used plenty of that, and lots of paper towels. It would be interesting to know the source of the stickum in the first place.

I agree with the isopropyl alcohol. However, it still does not come off easily. You can, with perseverance, remove the sticky down to the nice hard surface. I then used car wax on the cleaned areas and it worked great

The best solution I had for cleaning Bushnell Binoculars is Murphys' Soap. "Pure Vegetable Oil Soap" Household Cleaner. It has no toxic ingredients, no chemicals. I used it straight from the bottle. It removed all the sticky substance. I was pleasantly surprised. A lot of arm work.

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.

Vivitar binoculars housing very sticky old but never used


I have had a similar experience with Bushnell(NOT Vivitar). I called them and they offered to replace/repair them for a shipping/handling charge. If I remember correctly it was between $15 and $20. After pricing new ones, this seemed like a good resolution. I sent them in(my cost) with a check for their S & H. A few weeks later I had new ones from the manufacturer. I think there were a few years when the industry was using a "special armor coating" which turned sticky after a number of years.

Rubber housing on Sigma binoculars has gone sticky


  • Moisten a soft cloth with ammonia or Windex. Rub it over the sticky area to remove some of the damaged surface.
  • Ammonia can be used as well, but should be used with caution as it can cause damage to some plastic surfaces.
  • If the sticky, damaged surface remains, it can be scraped away with a spoon or dull knife.
  • Please note that these fixes are only temporary. Once the plastic starts to degrade, it will continue and the problem will be recurring. It is best to replace these parts whenever possible.

    The right hand lens came loose and fell off. Where can I buy a replacement?


    You can't get a replacement part yourself, the only fix is to return the binoculars to Bushnell for repair.

    If you're in the USA or Canada then your binoculars will be covered by Bushnell's Limited Lifetime Warranty; this applies only to the original purchaser and excludes misuse or any evidence of unauthorised repair attempts. If the warranty does not apply then you will still need to send the product back to Bushnell for a repair estimate.

    If you are outside north America, then warranties and repair processes may be different and you'll need to contact the Bushnell office for your part of the world.

    Note that as your binoculars are relatively cheap and can be purchased new for US $123.39 it may be better to sell yours on an auction site for spare parts and purchase a new pair. If you were not the original purchaser you then get the benefit of not only a brand new pair of binoculars, but the Limited Lifetime Warranty would also give you future protection.

    I hope that my reply has been of assistance, if so please take a moment to rate my answer.

    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

    I have an old pair of bushnell binoculars. only problem I don't know how to find them online they are silver like and come in a old brown case and they were made in japan. triple tested coated optics says...


    If you do an image search for Nikon Mikron and the one you have looks the same then you have a Bushnell copy from the 1950's called the Palm Pocket. These appeared in the 1950's. The 6x18 was available from 1951. The 7x18 and can be found in the Bushnell 1958 catalogue. By the 1965 catalogue they had gone from the product line up. If you look around the body of the binoculars you may find a code beginning with JB or JL followed by a number. This number will give the name of the Japanese manufacturer who made them for Bushnell. If you get the number go here for the codes

    The Palm Pocket came in 7x18 and 6x18 designs. A larger model the Broadfield was available with 25mm objectives
