This is a cheap, short-term solution that reduces buildup slightly, and makes it easier to scrape off. If you don't have a spray, rub on vegetable oil with a clean rag. WD40 or used motor oil have a similar effect, but they can drip off and damage your grass. Graphite, silicone, or Teflon sprays are all sold as lawn mower deck sprays (although the all-purpose product probably works just as well). Cover the entire underside of a clean, dry deck, then let dry as directed on label instructions. The effect is similar to cooking spray, but should last longer. If you are mowing a short, dry lawn, this may be enough to meet your needs. Check product reviews online before buying. Even products marketed for lawn mowers often due a poor job of long-term protection. If you tried a lubricant and were not satisfied with the result, check the ingredients on your rust protection product to make sure it isn't based on the same material. Follow label instructions for surface preparation and safety advice. No product has universally helpful reviews, and it's difficult to tell in advance which one will work for your mower model and lawn conditions. Here are a few possibilities:  A lanolin-based product such as Fluid Film leaves a non-drying coat. Some people swear by it, but others find that grass sticks even more to this coat. Test it on a small patch first.  Cold galvanization compound is a highly water resistant treatment for unpainted metal surfaces. This might be a good choice in wet climates, but dirt and debris may still wear it down much sooner than the label suggests.  Other heavy-duty rust protection products all have mixed reviews. POR-15 is one of the more popular options.
