A printer ink cleaner is a solution or tool used to clean and maintain inkjet or laser printers. It helps remove dried or clogged ink from print heads, nozzles, and internal components. By using a cleaner, users can restore print quality, prevent ink blockages, and ensure smooth operation. Ink cleaner products typically come in liquid form or as cleaning cartridges and are designed to dissolve dried ink or toner residue without damaging printer parts.
