Water and Mowers: Water and mowers are not a good mix. Whether your mower is a manual mower or a powered mower, water should not be used for cleaning. Just had an email from a customer who recently purchased a Brill Razorcut 38. She mentioned that she had just hosed down her mower.
Silicone Spray and Mowers: Silicone Spray and mowers are a great mix. Before mowing, spray the blades with Silicone Spray. When you are done mowing wipe the blades clean with a rag. Spraying first, cleaning last, will keep your mower going strong for many years. Silicone Spray can be purchased at the hardware store, it is right next to the WD-40.
