On my last post I mentioned that I turn the water heater up to get 140 degree washout temperatures. Well, the furnace guy is coming tomorrow to put in a new aquastat. The current one can't answer "how high is up?" Right now it's set at 90 and the pure hot tap water measures 124. When it gets too hot the pressure relief valve does its job - maybe a little too well! The picture below shows the cloud of steam in the cellar when that happens. So I didn't need the sprinkler can after all. The floor got a good, really hot wash.
Now, for your free moment of dye education: to wash out Procion MX type dyes, you really need water at 140 F / 60 C plus detergent. The very hot water breaks any partially bonded dye; the MX dyes are called fiber reactive because the dye molecules bond to the cellulose molecules.
That brings me to the free gift for signing up for my newsletter: instructions on washing out fabric dyed with MX. You can click the link in the upper right corner of this blog, or click here to sign up. I'll send you that PDF - and right now a real human still sends it, not a machine. Thanks!
P.S. I hope to post photos of some of the snow-dyes, but they must be washed and ironed first.
