Great tips here Thanks
I ve been what i ve been told is a chinese clone of the VPI RCM for a couple of years.
I ve been using detergents all this while but i ve assembled the stuff to make the proper stuff based on what i ve read in this great forum.

So I have the distilled water (from hospital lab, thanks v much) i have abt 2 L of rather expensive isopopyl alcohol ( made in the USA by Leica! for use in labs) and i ve got a bottle of Ilfotol off eBay.
Someone posted that they use ethanol instead of isopropyl (ispropanol)
Any theoretical difference ? if not would methylated spirit do ?
