Hello everybody. I just got a T8 used with an extra Japanese wheel almost new. Both wheels needed truing which I did but I noticed that the leather wheel was black and sticky from the previous owner. Research brought me to this thread which contains a healthy amount of information. Reading the last input from pnwPat I decided to try an easier way and it seems it works a treat so here it is.
I used brake and clutch cleaner which is a highly volatile liquid in a spraying canister that evaporates quite quickly and dissolves oils brilliantly. So I sprayed the wheel as it revolved and scraped the black dirt and oil with a stiff painting knife. A few cycles this way left my wheel almost in its original color within a matter of a few minutes with no stiffness at all.
I hope this will be helpful. <
