I haven't got any home remedies, but I would probably be tempted to take them to a local plater and let them do it. I have quite a lot of stuff re chromed, and they are used to stripping off the old chrome before they start.
I have never had something just stripped, but that sounds a sensible way to proceed. Most of the cost of re chroming is the handwork involved in prepping for the new chrome, so just having the old chrome stripped should be inexpensive.
It's interesting, in that we all buy tools that are chrome plated for durability, but amongst my really old tools, the unchromed ones seem to have lasted better. Steel quality seems to play more of a part in rust resistance than surface finish.
I have British made Britool wrenches from the 50's that belonged to my Dad, and U.S. made wrenches from the 30's and 40's by makers such as Billings, Armstrong and Blue Point that belonged to my Grandfather. None of these tools were chromed, but were in regular use up till the late 80's, show very little wear, and none of them rust!
I also have a number of adjustable wtenches, also dating from the 50's, by the British maker Garrington. The unplated ones definitely last better than the chrome versions. The chrome picks up chips (not surprising ovef 60 years) and if the jaws get dinked you can't just stone out the damage!
