A bit expensive but works flawlessly,
Verified Purchase(What is this?)
This review is from: Print Head Cleaning Kit for Canon Printers - 100ml (Office Product)
I have not given this product a perfect rating for the reason that it is quite expensive considering the kit is generally made up of off-the-shelf parts. Secondly, the Solution is definitely not enough to clean "30" Print Heads unless you use a couple of drops each time. But from my experience, you will need more than a Syringe or two to get a good thorough clean. So in the end, the kit does it's job well but doesn't last beyond say 3 cleans.
Yes, the seller does offer a £10 refund if it doesn't work, but honestly, I'm giving the actual product a rating and not his service.
Right, so the most important thing in this kit is not the Print Head Solution itself (as it's just a glorified bottle of Isopropyl Alcohol), but the Green round syringe pieces that fit directly on to the Print Head nozzles (see Product Image).
There is actually a specific way to efficiently clean Print Head nozzles. This method is also used in a couple of Third party industrial machines that are designed to flush ink cartridges for refilling later. This kit allows you to use the same flushing method on your Print Head, but sadly it's not emphasised in the instruction manual with which the kit comes with. For most people, the usual method of just using the Solution is sufficient, but I have found better results in using, what I call, the "Flush" or "Pressure Spray Method"
To achieve this, two things must be done to the Print Head nozzles;
1. They need to be rinsed in clean water, and then soaked in the Print Head Solution for at least one hour.
2. The Print Head Nozzles need to be PRESSURE SPRAYED with water to eliminate any internal blocking of clogged ink particles.
I will now take you through a proper step-by-step process to flush your Print Head (PH). This will GUARANTEE you a brand spanking new PH.
Note: If it doesn't work, it means your PH is just electronically damaged and needs replacing. If you're using a refillable ink kit like me, then it means your cartridges are over filled, or that your ink is cheap quality and unfit for use.
SEQUENCE 1 (A) - RECOMMENDED
Remove your PH and securely place the round rubber Nozzle seals in a paper towel, so that they don't fall off and get lost during the cleaning process. If you want, take a picture of the PH with your smart phone so that you know which position to put them back in.
SEQUENCE 1 (B) - OBLIGATORY
1. Take your PH to the sink. Open the tap on a low-medium setting, and rinse the PH for around 5 minutes until nothing but clear water drops off the nozzles. Just to be on the safe side, hold the PH in such a way so that the electronic part doesn't fall under the running water. Make sure no visible ink is left. After 5 minutes of rinsing, it should look clean.
2. Put the PH in a little flat container (Preferably 6-10" diameter)
3. Heat the PH Solution or Isopropyl Alcohol (99%). Fill the Syringe with it. Spray it all over the PH nozzles, making sure the solution goes in to the actual nozzles and comes out of the bottom nozzles. You should start to see more ink come out from underneath. If not, recycle the sprayed Solution and keep injecting it all over the nozzles. Now turn the PH upside down, and spray the Solution into the vertical exit holes too.
4. Leave the PH soaking inside the solution for around 1 hour. Don't tilt the container to one side. The nozzles need to be soaked in the actual PH solution.
5. After 1 hour, quickly re-rinse the PH under the tap. Shouldn't take more than a minute.
SEQUENCE 2 (A) - OBLIGATORY!!
1. Clean and re-install the round rubber seals on the PH.
2. Fill the Syringe with hot but not boiling water. Attach the Green round piece on to the end of the Syringe. Place the Syringe + Green piece on to a nozzle. With the PH in your hands raised above your sink, hold the Green piece down firmly. Make sure it's flat and totally covering the nozzle. Now squeeze the Syringe with PRESSURE so that all of the hot water sprays through the Nozzle and comes out of the other end like a jet stream. This is one of the most important steps in the whole cleaning process!
3. Do this successfully and you will see an equally distributed jet stream come out of the exit end of the bottom nozzle. Make sure the jet stream is equally distributed otherwise you have a blocked hole and you must repeat Sequence 1B.
4. Pressure spray each Nozzle 3 times until you think they are totally unblocked from the inside.
5. Dry it. Place it on a new set of clean paper towels.
SEQUENCE 2 (B) - RECOMMENDED
Fill the Syringe with more Solution, but this time, instead of spraying it all over the nozzles...you need to inject the Solution drop-by-drop in to the round Nozzle holes. Do not make a mess. Do it in such a way that you start to see the towel get wet from the bottom. This way, you'll know the Solution is cleaning and flowing through the internal ink passages of the Nozzles.
Let the PH sit overnight until it's fully dry. No need for any more water. The Solution will just dry over night.
TIPS: (i) Do not scrub, rub, or wash the electronic part of the PH (ii) Do not scrub, rub or even touch the round PH nozzles. You may damage the tiny pours. You're only supposed to let water and the Solution seep in to them. (iii) Allow PH to dry completely before placing back in to the Printer.

Thank you for such a detailed review. The instructions with the kit require 3ml per clean so 100ml should be sufficient for 30 cleans. Isopropanol is one component of the cleaning fluid, and declared for safety reasons, but neat isopropanol is not recommended for cleaning printheads.

The review you commented on was very good, but it might be worth mentioning that if you live in a (very) hard water area as I do, using tap water might not be a good idea; using distilled (expensive) water, or at least, de-ionised water (inexpensive) would probably be better.

What a brilliant write up, especially the more detailed instructions on how to clean the nozzles effectively. I wish I had found this earlier as I have already used one of the two bottles of solution. Would love to know exactly what other 'magic' ingredients are mixed with the Isopropanol and why, safety reasons excluded, it is not recommended for cleaning printheads. Anyway My first attempt has not worked so I will be using the remaining bottle for the 24 hour troubleshooting method in accordance with the instructions.
It is such a pity that Canon have ceased manufacturing a replacement printhead for the MP610 and its stable mates which were amongst the best ink jet printers they have ever made and certainly better than the flimsy alternatives currently marketed by them.
