Have NOT been successful in cleaning heads. Just using ink. How do I physically clean print heads on WF-4630

I saw that article but couldn't figure out how to get to sponges or print heads on the 4630.
I did think of trying to put windexon a mattefinish photo paper and print a color bar document .
I don't have matte paper, will need to buy some. Do you think this will work?
