I am no chemist but I've had or still have high mileage bikes that I used this same method every 15 or 20,000 miles to clean out. Brake cleaner isn't especially harsh and flashes off quickly. It doesn't harm fork seals and I don't usually have to replace them in any less than 80 to 100,000 miles.Thanks for the efforts in writing up :thumb:
I would like to check if using brake cleaner to clean the inside of the fork is generally acceptable. I did not remove the bottom bolt to release the fork piston, which I believed some old oil got stuck inside. Ended up the new oil was a little mulky after filling up as it was mixed with some old oil and junk at the bottom of the fork.
