Q – Should I oil my garden bench which is now a nice shade of grey?

A РOiling garden furniture gives it a protective coating but remember it will turn the wood brown again.  Teak can be left some  time if you really like the greyer colour but wood of less superior quality will gradually deteriorate if left untreated. You may have to choose between enjoying the more rustic grey colour of your bench or prolonging its life span which means changing its colour to one you are not so keen on.
