hi
I have never used that method however
I have used this method with great success

I had a couple of hp45 black carts and were blocked

I filled the sink up with very hot water and filled a syringe
up and put it in the hole at the bottom of the carttdridge
and began to squeeze the water into it .
I kept doing this until I had clean water coming out in
little jets like a rose of a watering can
then I shook it and left it upside down for a while then
filled it with new black in and sealed it
it worked a treat for me ..

( however you need a syringe that fits into the opening tightly
to make a water tight fit , , and be careful as if you put too much
pressure into the cartridge you may blow off the head )
let it dry before installing it .

my friend used this method for his Epson cartridge and again that worked
for him ....

haven't really had much luck at servicing a colour hp cartridge .
due to the sponge .

Some suggested IPA will soften and dissolve dried ink which I know is true
but I don't know if it would break it down small enough to pass thorough the
head
with out blocking it .

hope the info helps

I tried cleaning HP heads with an ultrasonic cleaner.
INK has to be soluble in the cleaning fluid. And if it's dry inside,
May never get enough backwards thru the hole to wet the dry stuff.
Can't say I was successful.
