Barry--in a couple of past posts you mention that "Window Cleaner" can be a more effective way to remove polishing oils than just a straight IPA wipe down, but I can't remember or find any posts where you go into detail about what you use or mix for this type of solution. So, do you still consider this to be an effective product for removing polishing oils? As an example, could one take 24 ozs of a 25% IPA mix and add .5 oz of 3D 50-1 Glass Cleaner (this would be a normal 50-1 mix) and use this as a more effective product for removal of polishing oils?? Or, do you have a recommended dilution ratio?
