Searching google terms like 'clogged printhead' or 'cleaning printheads' yields many many results describing how the use of 'isopropyl alcohol' will help with such.
A search like 'has alcohol damaged my printhead' yields many results about how its not recommended..
it can damage essential components
it causes ink to dry up so has extremely short-term benefits
So whats correct?
Does alcohol damage printheads or is it a reputable method of cleaning?
So your views???

Ive cleaned several inkjet printheads in isopropyl alcohol with great results. You mount the head over cloths remove the rubber ring where the carts sit and fill the head. Leave for an hour or so (top up if necessary) after which you drain the remaining alcohol and blow through with an air line. Repeat this process two or three times and rebuild.
