Hi All

I have some (ahem) mahogany garden furniture. Given the price I paid for it
at B & Q "mahogany coloured hardwood" is probably more accurate.

It's made up of 2" x 1/2" slats with cast iron end frames.

Its gone a kind of dirty grey colour over the last few years and I want to
restore it to it's original colour. Tried a belt sander with 80 grit paper,
but its very slow and is going to be difficult on a lot of the curved areas.
I don't want to dismantle it all (table, 3 x 2 seater benches & 2 x chairs)
and I don't have a thicknesser.

Pressure washer works but raises the grain a little.

Are there any chemical treatments or bleaches that would work?
