Looking at the post splashdown pictures on Columbia this week and I see the vehicle is mostly still covered in the Kapton foil, although looking worse for wear and tear of the mission.

It may have been covered elsewhere here, although I can't see specific information.

Can someone describe the reasoning behind its removal and processes that were undertaken to remove and save/dispose of the material?

A cynic might say so that little pieces of it could be sealed in plastic and sold for inflated prices to collectors.

I may be wrong but I believe that large quantities were pulled off the spacecraft after recovery by just about anyone who could get close enough to the capsule to grab themselves a souvenir.

Removal of the thermal control film after the flight was a required procedure. There may have been some souvenir hunters pitching in, but overall it was part of the post flight processing.

We have heard this film called Kapton, Mylar, foil, etc. It was actually a specially made material called GT-131 Thermal Control Coating Laminate. It was made by G. T. Schjeldahl Co. of Northfield, Minnesota. (Reference North American Aviation procedure MA0608-013, "Application of Command Module Thermal Control Coating.")

I've posted this before, but clearly the removal of the kapton by recovery team members as souvenirs was not planned for or authorized, as evident by an October 1969 memo written by Jim McDivitt in his capacity as the Apollo Spacecraft Program Manager:
There have been several occasions in which unauthorized removal of equipment or parts of spacecraft has been experienced. These removals have included stripping of small pieces of the kapton thermal coating and removal of the command module nameplates. These removals have occurred during the recovery and return to North American and during postflight testing.

I would like to point out to all personnel concerned that this unauthorized removal of equipment, no matter how small it may seem, constitutes a violation of our responsibility.

Also John, I have to wonder if it was part of the post-flight processing, why are there command modules in museums now with the Kapton laminate still partially attached?

It would have been required for access, dis-assembly to include dump and ablator plugs associated with panel removal, not necessarily the entire flight vehicle. Later post recovery procedures for the CM were very explicit however about protecting the heatshield (to include the ablator char surfaces) from further damage.

Of all the Apollo CMs recovered, does anyone know which one, as far as kapton foil souvenirs is concerned, would be the hardest to acquire?

I have seen some ASHURs that specifically call for removal of all of the film. I am presuming this would be true for all of the spacecraft, but maybe not.

By the way, keep in mind this isn't the registered "Kapton" brand of film. It's similar of course but technically not the same. Perhaps we should refer to it as thermal film.

Back in the 70's, I remember going to KSC and seeing the Apollo 13 Command Module. It was not covered with Plexiglas and only had a "short" maybe 3 foot tall Plexiglas wall around it.

I clearly remember many people reaching over to the command module and stripping off some of the mylar coating. Some even were poking at the Ablative Heat Shield on the bottom knocking off small chunks and taking them as well. The carpet underneath the capsule was covered with little pieces of heat shield that had been chipped away.

Years later on another visit to KSC, I remember seeing the Apollo 13 command module again and thought it looked so much different, and after comparing the two photos from the two different visits, I can see that nearly all accessible mylar had been stripped off by souvenir hunters.

This eBay item, which ends in three days, certainly seems like a worst-case scenario of what's being discussed here:

I toured the NASA exhibit of the Apollo 11 space capsule in 1974, and picked this piece of mylar off the capsule when I got up to it. I've kept it all these years, glued to a piece of poster board in a small plastic box.

Assuming that this story is true, he's clearly stating that it was stolen. But is it true? Was Columbia one of the capsules from which Kapton foil wasn't removed right away?

Columbia was transferred to the Smithsonian in 1970 following a NASA-sponsored tour of American cities. It was on display in the Arts & Industries Building until 1975, when it was moved to the new National Air and Space Museum for its opening the following year.

The photos of Columbia being moved suggest it was completely devoid of thermal film in 1975: 1 | 2

While it appears the command module didn't receive its plexi covering until after it arrived in its current home, the seller's account is either mistaken or poorly worded about where he saw Columbia in 1974.
