    so i got my dads old and basically unused n90 with the sticky film door syndrome. I called nikon to find out about them replacing the door as they used to do that. They had no idea if the facility had the part. also they said it would more than likely NOT be fixed for free and a fee would be charged. Does anyone know how much it would cost to fix if they could fix it? The cust service person was no help as expected. doesn't make sense to pay $100 to get it fixed as they are so cheap second hand. But a shame to not use it only because of the mess. how hard would it be for me to find one that is maybe non-working, take the door off and replace it myself?

    That problem goes way back to the early production models and Nikon did replace them for free. Now, though, there probably aren't any in stock since the N90s/F90x was discontinued 10+ years ago; if there are any at Nikon, I don't think it will be free. Replacing the door is the easy part; finding a NOS one isn't. The N90s/F90x is very cheap now--working or otherwise--so why not just look for another?

    Can't you just scrape the gunk with alcohol or acetone and end up enjoying a fine, silky door?

    That door comes off really easy, if you open the door and look at the inside of the hinge there is a silver thing that looks like a screw. With your finger nail pull that toward the bottom of the camera then gently rock the door and it should tilt away from the camera so that the top of the door is free. Then just lift the door up to free the bottom hinge pin.

    Assembly is the reverse of assembly.

    I would sell you my N90s with a nice not sticky door, but the door is all scratched up.

    FYI, I paid $65 for my N90s with a scratched but not sticky door.

    $100 is too much.
    I have a non-sticky MF26 data back I'd like to sell. $25 shipped USPS priority if your interested.


    Takes 30-seconds or so to switch doors.

    I had the same problem and cleaned gummy stuff with alcohol and few sheets of bounty paper in less than 45 minutes. And Yes, it's way easier if you take back film door off for cleaning.

    If you can get denatured (100%) alcohol, the cleanup will take less time.

    Thanks guys. Dont really need to get another on as i have 7 nikon film cameras already. but when i got it i took it out, shot a few rolls to test it out and then sent them off to costco for a quick development. Pictures came out perfect ( i actually have a pretty decent lab tech at my costco) so thought i would give the camera to my son to use. but man what a mess my shirt was. covered in all that sticky crap. anyway i'll give the cleaning ideas a try. and if they don't work, mark I might take you up on your offer!

    I gotta say though, this camera has a damn good meter. and for what they are selling for now, its a bargain

    I wonder whether someone like Akai-Asahi.com could manufacture film door covers for the F90?

    My vote is that if you can't stand the covering crumbling off, then simply take the door off and clean it. This would also be an excellent time to replace seals if needed too. I have one N90 that I have left the door as is with it's covering sticky and barely coming off and another N90 that I have removed the covering from. These cameras are not my go to cameras (my F5, FA and F4S are in that order now), so outside appearance isn't that big of a player for me for these cameras.

    My experience is similar to yours performance wise for the N90......perfect, infocus results. I love using them which reminds me I should probably run a roll of film through them....it's been awhile.

    I'm going to try the alcohol idea. Never was a big deal to be because it shoots perfect.

    Rubbing alcohol and cottong balls works well. I have used this on quite a few cameras with this problem.

    Just wanted to leave some info for anybody else who has the sticky back problem:

    - Since the phone support person couldn't tell me for sure, I sent in my N90s to Nikon's NY service center at the beginning of this year (2013) to see if I could get the sticky back exchanged. They would NOT do a free replacement. I received a letter with estimated charges to replace back and clean/adj. the camera: $200.

    (- I finally got someone on the phone from Nikon service after trying for about a week, I said I wanted to refuse the repair, but also complained a bit more to the person on the phone. The person on the phone offered to forward the problem to a supervisor and said I should expect to hear back in a couple days. 2-3 weeks went by, and just as I was getting ready to call them one more time, I received a package on my front porch. The unrepaired camera was inside with an invoice saying that the customer (me) refused repair.)

    - Following the instructions described in this thread (and elsewhere), I removed the back and spent about 30 mins cleaning it with isopropyl alcohol and cotton balls. Worked perfectly. The sticky rubbery stuff peeled away and bunched up sort of like a thin film of rubber cement. Back is now smooth black, not too slippery. There was a lot of loose residue, so you would definitely want to remove the back rather than clean around the edges with the camera open.

    - I'd read conflicting reports on this, but the little white mode symbols on my film back did rub off (you can still read the markings if you look at the reflections off the shiny back in some strong light).

    I used Goof0ff? on mine. It removed the covering fine and pretty much left the white symbol info intact.

    I second this advice. Alcohol and elbow grease cured mine. I actually prefer the result to the rubber finish. It is a lot of camera for the money and worth the effort to refurbish the door.

    It is a classic sleeper of a cam - titanium shutter with 1/8000th, and some of the best AF and metering Nikon's ever done.

    I too have done the alcohol thing. There are some thicker areas still visible, but they're not sticky anymore.

    One thing I found sped it all up: use 99% alcohol (many of us have that for cleaning), and cut some strips of plastic food wrap. Dribble the alcohol on, and then lay the plastic over - this keeps the alcohol from evaporating. Let it soak in for 10 minutes or so, rub & repeat. Speeds up the process for sure.

    The soft touch surfaces of the early 1990s weren't properly tested. I'm not sure whether they react with moisture from skin (aka sweat), or they just dissolve with time. I have three Sigma lenses of the era that have turned to jelly when no other lenses stored in the same box did. Nikon surfaces were made of similar stuff. Avoid both is my advice.

    Alcohol was not working for me. I used some very fine (P320) grit sand paper. It took an hour to carefully do the entire back but turned out really nice. Looks better than new and has a nice dull/matt finish.

    Alcohol and scrubbing with a toothbrush worked well for me. And it didn't remove the icons printed on the back door.

    The reason they used this rubber garbage is that at some point all the camera makers went to the same basic design scheme. Somehow a bar of soap was their model. And from there, "designer" soap. And as such, it was impossible to make plain leather coverings fit on all those crazy shapes.
