Place the cartridge on a clean surface and apply a few drops of alcohol-based hand sanitizer to the ink nozzle.

It's best to use an unscented hand sanitizer, as some scents or colors in the hand sanitizer may affect your ink cartridge's performance.

Gently rub your finger on the ink nozzle once or twice.

Let the sanitizer seep in for a few minutes.

While you wait, fill a bowl halfway with warm tap water.
