The only way I understand that stained wood can be returned to a natural state is by sanding it down to bare wood. Others in the know will be along shortly though. good luck

It is proper procedure to pressure wash (clean) a deck, and allow it to dry, before re-staining. Some information here, including recommended pressure: http://www.restore-a-deck.com/pressurewash.html http://www.power-pressure-washers.co...er-washing.htm __________________ - Build Well -

You will need a good deck stripper followed up with a neutralizer/brightener. __________________ To view links or images in signatures your post count must be 10 or greater.
