Neat bleach works. Wear old clothes, keep pets and people away, and paint
every inch
with neat bleach. You may have to apply more than one coat. Best not to
apply in direct
sunlight as it dries the bleach out too quicky.

Only use the plain hypochlorite ones - some of them have added caustic soda.

I'd suggest copper sulphate solution.

That really isn't a good idea. Copper salts inhibit the organic
chemistry in wood that protects it from destructive rot fungi.

I can't see what is wrong with a pressure sprayer with pretty boring
non-anionic wetting agent (or non at all). I still do not understand how
someone can get their garden furniture that bad in so short a time. It
must be dripping in tree sap to get that amount of sooty mould so quickly.
