Using bright Patrick's idea
, I was able to retrieve cotton from cylinder. It took some time, I used plastic straw (soon it will be rare item in New Jersey) and picture hanging wire which I had in my junk drawer (who doesn't have junk drawer? ). Before that, I tried straw and vacuum, but it didn't work. Suction couldn't overpower volume of this material ?
What I found interesting during working on injector(all the procedure with cleaning etc.) was difference in the length of a new injector bolt. I was suspecting, that the old one will be longer, not the other way around. I stopped blow by after 15 minutes of engine operation.It was probably some Black Death a little earlier cause I noticed erosion on injector sealing surface. Don't know if will be visible in the picture, but 2 spots I could easily see at a good light. At about 11 and 3:30 o'clock.
I managed to get rid of it, using fine sand round disc with center hole in it and hardwood dowel. It worked perfectly. I resurfaced cylinder washer seat same way.It had some imperfections. Came out very good. I use endoscope camera like this . It allows me to go inside cylinder and even injector bolt hole. Very useful.

This is my second repair, I did cylinder #3 about 20K miles ago. Hopefully this one will work well. I just did 20 miles, and all is OK.Too soon to say, but.. fingers crossed. And I always have 1 bolt and washer as spare-it cost next to nothing.
