Cheap fork seal cleaner and it's good for you!

Found both of my fork seals were leaking a little bit tonight. Started looking for something thin to wipe the dirt out and I noticed that the top of these tuna packets are very thin and strong. It's very stout foil for its size. You can cut the very top of the package off and not even open it up.
I know the wipers still on, but you get the idea.

Waxed business cards are great too. Yes, remove the wiper before cleaning the seal

A piece of tape measure tape about 6 inches long trimmed with tin cutters to resemble your little finger nail and scrubbed with steel wool to remove the paint and burrs will never wear out- works great- has the curve built right in.

I trim the plastic off the front cover of office presentations to about 1 inch wide and 6 long. Do a circumference of the leg (with the wiper down) bounce the fork several times and repeat the process about 3 times. Then do the wiper.
Some guys cut a piece of sponge that will fit into the void above the wiper and remove after several rides

Ive always used a piece of 35mm film. Now everyone's gone digital, I was trying to find some old film the other day for a piece. Finally scrounged up an old roll from the back of my junk drawer.

how often is should one do this?

So what was on it LOL

It was actually a new roll. I don't have a 35mm camera anymore so it didn't bother me to pull a strip out and cut it off.

Jesus cleans mine...

A riding buddy found a crate full of kids movies made for vacation bible school from the 60's and 70's on Super 8. He cut up sections and we probably have enough to supply every dirt rider with inverted forks in the world!

I run removable Seal Savers all year on all of my bikes and have zero issues, but will run the film up in the seals a couple times a year to make sure any little grit is cleaned out. Last time I had my halogen overhead lamp on and noticed Jesus healing somebody - maybe my fork seals...who knows!
