Everything you know is a lie
MYTH: This is going too far – I’ve always just blown on the cartridge and I’ve never had any problems. FACT: Blowing on a cartridge can seem to work – and if it does, it’s because adding a slight layer of moisture from your saliva temporarily improves the electrical connection between the cartridge and connector. However, this isn’t good for the long-term condition of your cartridges. A somewhat non-scientific test on the digital Press forums revealed that some nasty stuff can end up growing on your cartridges as a result of blowing on them, after just two weeks of daily use.
MYTH: I don’t have isopropyl alcohol – but it won’t matter if I just use window cleaner or something, right? FACT: We’d strongly recommend against it – those products contain chemicals that can damage your cartridges. isopropyl alcohol is sold for a number of purposes, and cleaning electronics is a widely recognised one. it can be bought cheaply and, when used in the quantities needed for cartridge cleaning, will go a long way.
