Sunlight, rain and overwintering have turned the wood grey on the

the under-surface of the seat, still a good colour.

So how do I get the colour back? A quick wipe over with the same Teak
Oil as I used last year isn't bringing it back.

- leave it be?

- remove the grey mechanically (sanding, cabinet scraper, broken glass, ...)

- oxalic acid. Beware the cautions, please.
