Those "cleaning kits" just have a surfactant in them. There are quite
a few varieties of surfactants out there, most of us call them "soap".
All they do is help the water wet the ink. However, if the ink is
really dry then they are a bit too gentle.

See my previous post about early version of Durabrite and glossy paper.

I strongly recommend -against- this! Patience, not force, is needed.

Sigh.... or you could rely on the experience of others.
http://www.polyphoto.com/tutorials/PrintHeadCleaning/1 part household non-sudsing ammonia (no lemon cr@p)
4 parts 50% isopropyl alcohol
5 parts distilled or filtered water (-not- purified water)
I taught myself what works and doesn't, with the best chance of
success without destroying the printer. Patience is a virtue. The link
above is a bit messy because it is saved responses that I got tired of
