Seized chain oil bath for how long?

    I had cycled through salted puddles and not noticed as bike was pretty clean. This caused ten speed chain to seize. Tried gt85 etc. no joy has been in an oil bath over a fortnight. Took out, some of the seized links now move, couple still stuck. Put back in bath. The Unseized links now very slidey. If I leave longer maybe will un seize them all. But still unsure the chain will be fixed as some links stiffer than others. The engine oil does now have little bits of grit in that presumably came off the chain.

    Anyone any advice?

    If they are still stuck, and presumably you've tried budging them with the strength in your fingers, I'm not I'd want to put that chain back on the bike.

    That said, perhaps brace a stuck link with something under it, support one side and give the other side a light tap?

    I once heard someone suggest a last resort of putting the oiled chain in the oven for 15 mins at 200 degrees and then trying a final flex of the links. No idea how successful that is. Care probably recommended!

    The "old fashioned" way to fix this would be to push the rivets out a little on any stuck links with a chain tool then push them back in again. However in the world of peened rivets and special joining pins most 10 speed chains would likely fail in use if you tried this.

    The oven or stove top is way of getting oil into the inside of the chain through expansion of metal. I can see that causing fire in Gembo Towers

    My sparebike's chain had once seized to the point of not being flexible with fingers even after WD40ing, but the regular slight gentle persuasion of leg-power braced against metal meant it was fine after riding fifty metres.

    Hopefully if I put it back on that will be what happens but it was very bobbly through the jockey. Quite annoying as relatively new chain.

    How much are new chains?

    If I went on tinternet 15-20. But this one was a support your local bike shop scenario and cost me thirty quid. Hence my attachment to fixing it. There is a school of thought that you should always keep a chain in a bath of oil. A chain on your bike and another chain new and rotate them. I am not an adherent of this school but it does get some attention?
