Will cause burns, don't recall a dead fish label on the back, would have to check, however washing up liquid will kill fish...
I'm not sure what points your trying to make Chris, and Im not really interested in being used as a means to score cheap points against other members of the forum,
Kevin supplied me with information on tackling a job I've not done before, after looking at some options and products I brought from Kevin - this thread was about thanking someone who had helped me out with advise, not a product bashing exercise..
Roger has done the same regarding a large Ipe deck job. And rob gave some guidance over a van mounted pressure washing system, all these guys get my respect because they give sound advice without expecting anything in return
Hope this helps
