FWIW, I inherited some Look-style pedals from Kudude (extremely kind gesture, btw). I used 'em for a month and I had set them on the lowest tension, but was still having some problems getting in and out. Finally a kindly LBS guy suggested some cleanser to remove grit (wish I could remember the name, comes in aerosol can) and then some Boeshield T-9. We flooded the clip mechanisms with both, let them drip out, and voilá -- clipping in and out was suddenly *literally* twice as easy.

This will only be handy for those whose pedals have some age on them.
