Printhead Cleaner, Original Print Head Clog Buster / 4 oz. bottle.

Print Head Clog Buster is the original formulation that Epson and most printer repair shops use. This is not a Chinese import but the original American print head cleaner that works on all inkjet printers except wide format printers using solvent based inks. This will also dissolve sublimation ink. Print Head Clog Buster is not for Laser printers or for printers using solvent based inks. You can also fill empty cartridges with Print Head Clog Buster and use in the printer as a cleaning cartridge. Please be aware that if your nozzles are badly plugged or have been plugged for months or years that it will require more time to dissolve the hardened ink deposits. I have successfully unplugged printers that have sat for 7 years without use and after 1 month of treating the heads with both our cleaning cartridges and applying Clog Buster was able to get a perfect test pattern.
