Wash With Water

Drying The Deck

Air Dry
Air drying is a simple method. Just leave your mower in a sunny, dry spot. The heat from the sun helps evaporate any water. This method works best on a warm, breezy day. Make sure the deck is raised to allow air to circulate underneath. This ensures every part of the deck dries thoroughly.
Use Towels
Using towels is another effective way to dry the deck. After washing, take a few clean towels and wipe down the deck. Focus on all areas, especially corners and edges. Towels help remove excess water quickly. This method is great if you need to use your mower soon. Remember to use dry towels for the best results.
