My cruiser fork seal started to leak in 2004, with only 3,000 miles on the bike.
I used the same cleaning method, but with a piece of old 35mm film negative cut to the same shape, and a thick paper business card cut to this shape also works.
This fork seal is still not leaking after 8 years and about 23,000 more miles.
"Until he reached thirty, Randy felt bad about the fact that he was not socially deft. Now he doesn't give a damn. Pretty soon he'll probably start being proud of it." from Neal Stephenson's Cryptonomicon novel (1999).
