Forks : Removing Bushings (the thin metal lining inside sliders/fork legs)
When servicing forks, it can sometimes be a RIGHT BITCH to get the bushings out. They are sprung by nature and when covered with oil they 'stick' to the inside of the sliders. They are made of very thin and delicate aluminium (usually) so its a bad plan to use a tool to 'poke' them out. Instead, remove all seals and washers sitting above the bushing, hold the whole fork by one slider (leg) and tap the disc mount in a downwards motion with a rubber/nylon/wooden mallet. You don't need to hit it hard and the bushings will just pop up.
Note: If you don't have a disc mount just put a quick release bolt/lever across the forks and tap that.
 

 
Forks : Polishing Sliders (legs)
It doesn't take too much for the polished aluminium finish on many forks to get a bit tarnished and spotted. Heres a few notes about bringing them back to an 'as new' condition:

When lightly tarnished: AutoGlym 'Metal Polish' (available from Halfords) is probably the best thing under the sun for this. Apply it with a rag, polish, and then buff it off with a clean piece of cloth. I have found the finish to be WAY better than Braso, Duraglit, & T-Cut.

When tarnished and scratched: If you have scratches on your polished bits (ouch), you can take them out with wet&dry. Grades 400, 800 the 1200, should leave you with a great finish ready for polishing. Finish them off with a spot of the mighty AutoGlym.
