What is the procedure for home repair of Hewlett Packard #14 print
heads?

My CYAN stopped printing (even though the refilled cartridge is full)
and a diagnostic report from the HP OfficeJet D145 all in one printer
says the CYAN print head needs to be replaced.

Since the print head has to be replaced, I may as well attempt a home
repair. But how?

A friend suggested I remove the bad cyan printhead drip a solvent such
as alcohol or acetone or hydrogen peroxide on the top steel grid until
it runs clear - which might unblock the screen in case it's blocked by
teeny tiny honey-I-shrunk-the-kids debris.

He said then to gently swipe the bottom of the print head with the
solvent so as to free up goldish metallic strips on the bottom.

Is there a published procedure for home cleaning & repair of print
heads as a last ditch effort before replacing them altogether?
