need to clean L1 bridges

[biassj]

There's probably tons on this but I don't have the time to look around.
What's the best way to clean the L1 bridges????
I used a pencil for the L1 bridges...

As stupid as it may sound - a pencil eraser.

What ever you do don't use any solvents or cleaning fluids. Does not very nice things to your chip :)

Hope this helps.
