there I found out that they use a wood for their outdoor products
that is pickled.

interesting never knew that but it explains a lot

took a part a swing and tower set and could not figure out how the
wood was treated

i think this pickling is the answer

it was also kiln dried and after twenty plus years no bugs and no rot
just some warpage


Though my memory of the details could be off, as I recall the wood
itself is from Austria and the preservation is done in Norway... This
not a finish but rather an impregnating process (I believe done under
a vacuum like pressure treated wood). When I smelled the wood it had
the scent of pickles/vinegar.

this stuff had an odd smell and maybe it was vinegar

For pallet wood it might be cost effective compared to heat treated
wood... perhaps this is what you have.

that does make sense because they want pallets to be cheap
