Dale,I've used several different soaps over the years,the one I'm using now is made by KO.Its a good soap,I've used Delco its a good soap,Allotect makes a good soap also.The one I'm fixen to try is made by Bluff City,I'm sure its a good soap also,meaning alot of good soaps on the market.I have yet to find a good soap at a cheap price and have yet to find a liquid soap thats better than the powered soaps.
The rules doesn't say you cann't name a soap on the board,if your saleing or pushing the product its a different story.
Everybody doesn't use the same soap,it doesn't mean they aren't useing the best or the worse,it means they have found one they like.Last year I give 150 for a 5 gallon bucket of liquid soap,it worked ok but not like I liked.Like Tony said,I don't think there is a perfect soap,they are getting better at making good soaps tho.
