Where can I buy some Wood Bleach in West Yorks?

Ask snipped-for-privacy@rustins.co.uk for a local stockist. Or Liberon if you can find a UK website. You may find hydrogen peroxide (part2) at an agricultural wholesaler, and you can use caustic soda or washing soda for part 1. Certainly cheaper that way.

I doubt it. You need about 30% for best results, 20% to be at all effective (one reason why you shouldn't buy old stock).

Best I've ever found on the "diseases of sheep's feet" aisles was 12%. Usually it's just 6%.

Got some @ Morells-woodfinishing in Leeds. 5L of A and B for twenty squid.

cheers

A few tips. Get yourself a pair of synthetic fibre brushes. Both a and b will destroy ordinary bristle. Use plastic gloves. Part B stings. Leave partB to dry completely before assessing the results Decant what you need from the main containers, and don't pour it back. The smallest trace of partA in partB will cause the container to swell and lose strength. The cap should have small holes in it to allow the gas to escape, but keep an eye on it. Good luck

cheers, I used it Tuesday (google groups of this ng was good for advice) and I am quite pleased with the results.
