You can, but no telling if it will really do anything. I've seen it actually cause grass and dirt to stick to the deck.
The best things you can do for a mower are this:
1. Scrape off any grass from under the deck before long term storage (like over winter). Tilt the mower carburetor side facing up so oil from the engine won't dump into the carburetor when it is on it's side while you scrape out the grass.
2. Only mow when the grass is dry if you can, this will prevent grass build up under the deck.
3. Keep the oil level full.
4. Run the mower out of gas before long term storage to prevent carburetor issues in spring time from moisture contaminated fuel.
