This review is from: Liberon WB500 500ml Wood Bleacher (DIY & Tools)
After stripping the coloured varnish from my 20 year old marine ply dinghy, I was left with large ugly black patches where water had penetrated and stained the wood. Also there was stubborn yellowish wood stain that I couldn't seem to get rid of without sanding through, which is not recommended, as the outer ply veneer is decorative and very thin. I applied the wood bleacher as per the instruction - nothing happened at first, so I left it to dry (again as per the instructions). The next day I could hardly believe the transformation - all the black had disapperaed, and the yellow stain had gone. I wiped it over with a damp cloth then sanded it a little. The result is extraordinary - I have what looks like new wood to start the re-varnish job, which will be clear this time round. I know it's based a simple solution of oxalic acid, but I would recommend this Liberon stuff to anyone.
