That is ok.
I have experienced what I described and others may have other experience......only time will tell.
End-of-life is a critical part of the technology product lifecycle
This is a test-print 10 x 15 cm printed after Nozzle Checks, new refilled cartridges with mixed dye-ink from different suppliers. Scan is done with the same printer - MG7550
It takes time to desolve cloggs......
This is my recent Nozzle Checks with an old printer(MG7550), then after 24 hours and finally after additional 48 hours......soaked in Ajax Kitchen
I am located in Norway.
"Ajax is a brand of household cleaning products and detergents made by Colgate-Palmolive. The brand is also licensed by Colgate-Palmolive in the United States, Canada and Puerto Rico.[1]"

It feels like I have tried almost every dissolver mentioned in forums, FB-groups or Youtube during the past years, but when it was time to unclogg my Epson 4900 I realized I needed something more "powerful" fluid to clean the inklines inside the printhead. Ajax Kitchen....did the job thoroughly.
