I have various wooden items in my garden: raised beds, supports for runner

The wood I have used was all treated (tanalised?).
What treatment would people suggest for not just painting the wood, but soaking
in and protecting it from rotting? Named product recommendations appreciated.
Cheers.

All the really good preservatives have been banned.
The bits that really need treating are hidden unless you are prepared to dig them out.
Cuprinol is good (ish) but expensive.
But not as good as it one was.

If your tanalising was done years ago it was good (Arsenic and copper salts.)

Nowadays it is **** (Chromium salts I think.)
