    I have what seems to me a rather odd question. Hopefully this is the right place to post it.

    Some time ago I purchased a TC bundled with a step-up ring for the SEL 55-210. I recently discovered the ring had been literally glued to the TC, presumably to keep it permanently in place. Not a terrible idea I suppose, but I wanted to remove the step-up ring. So after some difficulty I eventually managed to work the ring off. There is quite a bit of residue left behind and I would like to remove this.

    Any idea for a fluid I can safely use that might remove whatever bonding agent was used without damaging the ring or TC threads? I tried rubbing it off but I can see that might take considerable time and effort and probably not get it all. I wish I knew what glue/cement it was for certain; it feels a bit rubbery between my fingers, and there appears to be a bit of red coloring to some bits, but only in a few spots. I would be very careful to keep any cleaner I attempt to use on the outside edges of course, and try it on the ring threads first, but the safer the substance the better. I think the TC and ring are both made of a very hard plastic.

    My first thought was fingernail polish remover but after reading about the damage it can cause to all kinds of things especially plastics, that does not appear to be a good idea. I saw lighter fluid suggested somewhere - not sure about that either. So mainly just looking for ideas if anyone here has knowledge on this sort of thing.

    If I cannot be sure using something will not damage them, I will resign myself to leaving things as is, but if there is something safe and preferably easy to obtain I would like to try removing the residue. I could stop by the one local photo shop here in town and see if they have any bright ideas, but I do not believe they normally do repairs or lens cleaning so they may not know much about this either.

    I've had pretty good luck with Goo Gone.

    My wife uses that stuff all the time. Why didn't I think of that? I will check that out, thanks.

    Warming up gently with hot air?

    I posted this question one other place and someone suggested that. I had not heard of that to remove anything, just loosen which I had always thought was due to expansion coefficients. I think I am going to give that a try this evening.

    So for anyone still interested... I tried Goo Gone but it had little to no effect. I also tried heating it up a bit with a blow dryer then using a small tool to dig the goop out of the threads. It helped in the areas where there was a thin coating, but the thicker areas have proven a bit more stubborn than that.

    Someone elsewhere though lighter fluid was worth a shot and would not harm anything. I do not have any lighter fluid in the house, so I may pick some up this weekend and give it a go.

    From your description of it, it's red Locktite. Red is the permanent Locktite, not meant for disassembly. According to the manufacturer, the way to loosen red Locktitle is to heat it to 500F or so. If Goo Gone doesn't do anything, I don't think lighter fluid would. Same active ingredient. Acetone will do something, but it would be slow going and it will damage other plastic. Methylene Chloride will chew through it but will definitely chew through other plastics as well. Methylene Chloride is pretty nasty stuff. There are plastics that are resistant to these solvents, they come in plastic bottles after all. The question is whether the plastic used to make your TC is one of those resistant plastics. I would tend to doubt it.

    The further into this I go, the more I think I will just leave this sucker permanently attached and just use additional step up/down rings. Its gotten to be where it is not worth it.
