Walterjn cheap rubbing alcohol,................................run alcohol through it to get rid of the ice.
Walt, never use 'cheap' alcohol for that. Read the label..........inert ingredient is...........water!! You are putting water back into the lines. '50%' alcohol is also 50% water.😲
91% alcohol is all I use. I use it for cleaning hosels after prepping. I don't want any water in there for rusting. And yes, I realize it evaporates, as far as we can see, but it was still in there.
