This worked well to clean the printhead on my inkjet printer and I'd give it five stars, but there's a big problem with the instructions: the instructions require you to preheat the cleaning solution in hot water , 176-194 °F. It's too hot: At 150-160°F (measured), the heat and internal pressure caused the plastic bottle to warp, the cap began to leak, and I had to cool the bottle down quickly. under cold running water, then pour the cleaner into another container. I ended up using the cleaner at room temperature and leaving it in the printhead for 12 hours. Depending on your printer model, you may need to run multiple printhead cleaning cycles (it took three cycles on my Epson WF-3640) to completely wash out the cleaning solution.
