That's why I wrote that they are clean, I keep that in mind, but thanks for noticing.

You said "mostly clean" and I assumed that this was about dirt and debris, and the stuff they're treated with is not visible. There is a stamp on the side which shows how they have been treated, though.

True but it's very much not all pallets. EUR pallets are mostly heat treated. Some are methyl bromide fumigated but that is banned in Germany.
