6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your garden cart.
- Cleaning: Wipe down the metal frame and plastic seat with a damp cloth after each use to remove dirt and debris. Avoid harsh chemicals that may damage the finish.

- Fasteners: Regularly inspect all bolts, nuts, and screws to ensure they are tight. Retighten as necessary to maintain structural integrity.
- Lubrication: Apply a small amount of general-purpose lubricant to moving parts such as the steering mechanism and seat swivel point annually, or as needed, to ensure smooth operation.
- Storage: Store the cart in a dry, covered area when not in use to protect it from weather elements and extend its lifespan.
