Grass build up

[geezer]

I spray the underside of my mower deck several times a year with pam to stop grass build up. It works very well.
Was wondering what others use.

water spray, homemade scraper, rags

Nothing!

However I have a Polypropylene deck, so that is naturally glossy, and grass never sticks to it.
