It looks like I am stung with the Vintage bike bug....

I have two Rigida rear wheels with Maillard hubs. The date stamps are 51 78 and 03 86 respectively. They look like standard Maillard hubs to me (no Helicomatic)
I want to remove the freewheels of both to clean them. I have a few questions:
1. Is this worth doing? I planned to clean the freewheels in some strong solvent/oxalic acid or the like and then put them back on.
2. In some previous thread I read about a freewheel removal tool from Bicycle Research Tools (CT-3) (see http://www.bicycleresearchtools.com/wheelt.html) that would work on Maillard hubs. The description says that it is for Normandy hubs. Will this one work on Maillard hubs

As always any help is greatly appreciated.
