A3: After each use, pour any leftover product back into the original packaging and wash the spreader thoroughly over the lawn to remove all product clinging to the spreader, particularly around the axle. Hot water may be required to remove stubborn residues. Allow the spreader to dry before safe storage. Lubricate the axle bushings regularly using a light spray lubricant. Do not use heavy oils or grease as they can attract debris, which can cause premature wear.
