Which is the method to clear or cleanse the head of ink cartridges for refilling of the black ink?

I have a few blank ink cartridges. The refilled cartridges cost only 5% of the price of a new cartridge but when I went to get the cartridge refilled, the technicians told since the head of the cartridge is jammed, the ink won't flow from it and there will no prints.





I want to know if there are some methods or chemicals to open the head of a black ink cartridge so that it may work again.Which is the method to clear or cleanse the head of ink cartridges for refilling of the black ink?

Hello:





I agree with the other poster- use a Q-Tip with alcohol. But, in addition, I soak them in alcohol first for a few minutes by setting the cartridge, ink jets down, on a heavily alcohol-soaked rag. I do not recommend dipping the cartridge in alcohol, as this may end up attacking the plastic.





I use Denatured Alcohol, which you can buy at nearly any hardware store. You'll find it in the paint supply area.





Caveat: no cleaning method is perfect with those things. I've had some of them fail to clean up no matter what I've done.





Cheers!
