and the handles of my tools get a think layer of some sort of mold on
them. It's like a grey dust. (Or some other light color, I forget.)

Does it look like this?

The former I always attributed to some kind of persistent "moldy"
like white paste (which I've long ago painstakingly scraped off
handle that tool you see in the picture so that only remnants remain)

The other is on my pool pump - which - you can imagine - isn't
mold but a white chemical covering (calcium carbonate?).

So, the first question, is whether it's a mold or a chemical?
Note: I don't know the answer for either of my tools above.
