It can be worse for the interface on your crank arms than your BB.
Assuming all your chainring bolts are tight, try putting a drop of light oil (or even chain lube if that's all you've got) on each one where it makes contact with your chainring.
It's also very possible that your BB isn't fitting into the frame as snugly as it should. You may want to try teflon tape (like what plumbers use) in place of grease.
