Saved me from sending my printer to landfill. Also saved me spending $ on a new printer! Initially took a few prints to get working properly, but perseverance pays off. (Soaked for a whole day). The test prints got better and better after the clean. I printed out a large photo to help blow out any other cleaning liquid / contaminants out. Now my testing print lines are perfect.

Used this for a Canon TS9020 printer, and it worked fine. I made sure after I cleaned heads & before I reinstalled into printer I used a blow dryer on medium setting to dry up any wetness left by the solution. I was a bit skeptical because this print head had not been used because of being clogged for over 4 months. Now it works perfectly.

Looks similar to the homebrew airbrush cleaner that we use to clean out acrylic airbrush paint: excellent money-saving idea. Since my wife died I don't print 1/4 as much (she was a crafter, and I would print 500-700 sheets every month) Thank you for this.

Homemade cleaner made with distilled water 99 parts and ammonia 1 part mixed 8 parts to 2 parts rubbing alcohol (Isopropyl) and squirted with syringe through head worked great. The syringe added pressure that was important. Thank you!! HP 6962

You want to use the Windex with amonia (Amonia-D is just the trademark name for amonia). I think, whether it's marked or not, most Windex has some amonia in it. Regardless, you should actively try and use glass cleaner with amonia.

The Windex and alcohol worked like a charm in a plastic tube left overnight. I didn't have a syringe so I used a can of air spray to push the liquid cleaner through the ports. What a difference it made with my Epson R300 printer. Like new printing again!

I have tried this formula and it works to an extent but for a short period of time before requiring re-cleaning. I recently and stupidly tried to clean my print head with WD-40; it totally clogged the nozzles and so I tried this and similar formulas to no avail. So I concocted my own; I used very hot water with a large amount of cheap bargain brand dish soap and a couple ounces of rubbing alcohol (91%). I added no ammonia although that was to be my next step. I pushed it through the nozzles using tubing that fit and syringes with luer lock tips and connectors. I used several ounces on each nozzle and rinsed extremely well with very hot water. After drying the head and doing a standard printer cleaning it has worked well and has remained free of clogs past the point of other cleaning methods.

Did surgery on my Workforce 645.  This stuff worked like a charm.  Thank you for sharing.

1 part ammonia, 9 parts de-ionized water (distilled should also work), 2 parts isopropyl alcohol,

My printer hasn't worked for WEEKS! Thank you Thank you Thank you!!! Its working again!!!

Awesome! Worked perfectly. Saved me from buying a new printer. After I was done I gently dried the carriage with a hair dryer set to cool. Thank You!!!!!

word of caution when using windex, it will dissolve the protective coating inside the nozzle which is there to prevent oxidation. alcohol is only good for surface cleaning, but it tends to turn pigment ink into jelly and it can get really stuck if you're not thorough with cleaning. the best solution is heated (not boiling, but pretty warm) distilled water.
