Remove All Conditional Formatting From Sheet At Once?

I am attempting to remove all conditional formatting from a sheet. Over time as data has been copied and pasted, the conditional formatting has gotten out of line and now there are hundreds of rows of unneeded conditional formats. The problem is that the only way I know how to delete each rule is to click each item on the conditional formatting rules manager and hit delete. This takes forever. Is there a way to remove all at one time?
