I guess the shorter way to say it is the tools gets contaminated.

Well, that's too easy to correct. Polish the tool heads before using them on the AL.
I face the issue in welding. Have to keep wire brushes, etc. separate. If I had a file I would just clean it with brake cleaner and acetone. Now a file is an extreme example. If I was talking about a hammer that would take 15 seconds to decontaminate from steel particles. But you're correct, it's easier to not go through this if you do enough AL repair.
The real problem with AL is that it has no memory. Steel does and incorporates stresses when bent or dented. These stresses are used to the advantage of the PDR method. Working AL is the same as initial metal shaping.
I've gone down this rabbit hole before your thread. Very tedious as if PDR wasn't tedious enough.
