Review on 🖨️ JINHEWEN Printhead Cleaner Kit for Canon/Brother/Epson/HP Inkjet Printers: HP 8600/5520/4620/6520/6600/6700/6968/6978/8610, Canon MX922/9000/C88 & More (100ml) by Dewey Tory

The printhead cleaning kit contains all the tools you need to clean your inkjet printer. You need to use some force to attach the nozzle to the syringe. For the other side of the nozzle, you need to insert the thicker side of the included L-shaped adapter into the nozzle and the thinner side into the yellow part (or the transparent part depending on your printer/printhead model). I used the product to clean a 5 year old HP printer. The solution thoroughly cleaned the color heads and now the colors match perfectly. Color print quality has improved significantly. The black still seems to clog, so I add a few drops every hour for a day and let the solution sit. I am happy with this purchase and would recommend it to anyone looking to manually clean their inkjet printheads.
