There are other cheaper machine system cleaners out there. Check the internet...... I thought that Blaser was sold on the premise that it contained "good bacteria" that ate the bad bacteria!
It sounded like BS when the Blaser salesman came a calling. Surely all organisms like bacteria eat and crap in the coolant which causes the spoiling of the coolant.
Buy Rocol coolant.....it does what it says on the box.
