Before the German method of refilling Canon BCI cartridges was known, I gave up on the normal way of refilling which was to make a refill hole in the top of the reservoir that has to be securely plugged up after refilling.
Instead, I refilled large numbers of cartridges at one time using a vacuum technique which you can read about here:

I continued to use this method to refill after the German method was discovered because I thought it would have the advantage of eliminating the need to purge cartridges that would no longer flow, presumably because of air or dried ink embedded in the sponge material. I thought the vacuum would get rid of the trapped air and the flow of ink through the sponge material on its way to the reservoir would effectively purge the sponge material automatically.
This proved not to be the case. My last vacuum refilling exercise was for about 35 BCI-3eBk cartridges refilled with Inktec pigment black ink. Unlike my previous refillings in which I used virgin cartridges (those that had never been refilled), I used cartridges that I had previously refilled and were now empty. When I got done, I tested each cartridge by putting it in my MP760 and running the scanner with the scanner cover open which should produce a solid black printout. About half the cartridges worked perfectly but the other half had what look like ink flow problems. Try as I may, I could not get any of these cartridges to work correctly. So now I know that vacuum refilling will not rejuvenate a cartridge, at least not one filled with pigment ink.
As a side note: I had left these 17 cartridges sitting with their outlet ports untaped because I would periodically test them but to my surprise, the ink level in all the reservoirs went down at a very rapid rate. In just a few months, the ink was all gone. This was not from printing anything. I figured that the outlet ports provide a good evaportation site and the ink inside the sponges now must be super concentrated. I'll never do that again. Don't leave your cartridges unprotected if you plan to use them again.
Now I'm switching over to refilling via the German method. I've only done a few so far because I still have a large number of cartridges still left from vacuum refilling.
One of the other reasons I like the German method is that it doesn't get ink in the air vent serpentine path or in the wells along that path. It is a lot of work to clear the ink out of there but now I don't have to do that with the German method.
