Yes i have had 2 letters from the Woolsafe Org regarding using woolsafe products as solutions uk in which i use a lot of their chemicals, are not renewing their woolsafe membership on chemicals , this only comes into play when cleaning wool. When i joined Woolsafe, the chemicals i was using was not an issue as they were all approved by Woolsafe,and M power and Nemisis were not on the market.I do not blame the Woolsafe org. for enforcing their regulations as they are protecting their good name,there is more to being a woolsafe product in their defence than a neutral PH,which can be buffered as other things can break down the fibres.For me ending my Woolsafe membership would proberbly cost me work for a carpet retailer who also advertises my company for free in their shops,also there is litrature, business cards,websites,signwriting would all have to be changed .Then there is the small matter of having a insurance claim against you on say a rug bleed,If you have not used a woolsafe product when cleaning, your insurance company might not cover you.
