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!!

Oster wine opener sticky rubber surface


Did anyone have an answer to this? I have had the same problem. I like the opener, but the parts of the rubber surface that are not usually handled get quite sticky. Any thoughts on preventing this, or if not on removing the stickiness?

Mouse Body Is Sticky How Do I Clean It?


I had the same issue and using clorox wipes only made it worse. I eventually used Lacquer Thinner, which is usually a mixture of solvents able to dissolve a number of different resins or plastics. It can be purchased at most home improvement or hardware stores. It worked perfectly.


It is a bit of a messy process and there are fumes. I wore rubber gloves and did it in my garage using several paper towels. I also recommend applying scotch tape to the edges of the non-rubber areas to protect the finish. Also avoid getting it on the bottom of the mouse.

The rubber casing has gone sticky


Many cameras and binoculars are covered with a sprayed on thin layer of rubber which breaks down after about 5 to ten years. It becomes very sticky and can be scratched off with a fingernail. This leaves a messy surface which can be cleaned off with methylated spirits. Other solvents will work like isopropyl alcahol but avoid using solvents like cellulose thinners or white spirit as this can attack the underlying plastic on some cameras.

The battery cover as bowed i need to keep my finger pressed on the cover to take pictures if i dont keep my finger pressed on the battery cover the camera swiches off


it seems the battery box are a little loose for the battery, you can add some thing(such as small piece ) between the battery and the box to let the battery and camera connect well. Don't block the joint between battery and box is OK

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.

Praktica view pix (keyring) driver


I have had the same problem, unable to load the small CD for the Praktica Viewpix digital keyring. I have today phoned the support line, and they have given me a separate web address where you can download the driver.

The address is:
www.jpsupport.co.uk/praktica/drivers

the correct driver to download is:
photoviewer v 2.24.exe

I have downloaded the driver successfully and am about to try and run it, although I am using a virtual pc on a mac so it may be slightly more complicated for me.

Hope that helps some of you though....
