Readers: I can only remark again that in years of steam cleaning I personally have never destroyed any vinyl that I steam cleaned. I have stressed the vinyl every way possible without any negative consequences. The only exception was an experiment using a steam iron a emailer professed was far superior to using a hand held steam cleaning unit. Yes, he suckered me in and I deserved the consequence, a melted vinyl LP. The whole experience taught me , be careful from whom you accept advice , some ain't worth the price of s---. It is for this reason and many others I stress the K.I.S.S. method ( Keep It Simple Stupid ) .
Repeatable results require repeatable steps. I wish I could repeat a steam cleaning that destroyed a vinyl LP but as of today I have never been able to do so except with a steam iron. And friends never forget that in the world of business there are those that want to destroy any idea they don't control all for the sake of money. In the film "Iron Man" Jeff Bridges torments the hero " Just because you invented it doesn't mean you have a right to keep it".
