Again about WSS, the one I am using need very,very hot water, is there some that need only cold water?

I've always used warm water. I usually buy it from my dealer so I don't know who makes it.

I thought just warm water was fairly normal, but maybe you need to soak it longer, like overnight? Best of luck.

H2O be gone, which is found at Wal Mart (those that still have fabric) washes away easily with warm water....Solvy WSS found at JoAnn also washes out easily.....I hope this helps.....blessings Janet
