Information for anyone ...
In the last couple of years denatured Ethanol (alcohol) was made legal for use anytime. I questioned the USBC on this because I knew it had been ruled illegal for so many years. Also , the ingredients that are commonly used to "denature" the alcohol, like gasoline, MEK, Acetone, are still on the "not approved ever" list.
USBC said that they found that the denatured alcohol did not change the surface in a way that would make the product illegal to use.
I still tend to disagree..Why make a product legal to use when some of the products in it are illegal.
I also read an article about 5 years ago that said it wasn't good to use denatured alcohol to clean newer reactive resin balls because of the additives like MEK and Acetone. They will break down the surface and the cell structure and basically melt the surface smooth and take the porosity out of it.
See the "commercial products approved at anytime" listing.. 4th entry down
Also, the reasoning for the soaker balls in Tuolulene was to create a softer cover and thus creating a larger footprint on the lanes and more friction. The soaker balls is what led to the hardness specifications in the PBA and ABC.
