To properly expand the sponge, follow these steps:

• Carefully take the sponge out of the sealed bag.
• Immerse the sponge in a container filled with water, ensuring that the entire sponge is fully submerged.
• Allow the sponge to soak for several minutes until it begins to expand and soften.
• Carefully remove the sponge from the water and gently squeeze out any excess water.
• Rinse the sponge with clean water and squeeze out any remaining water.
• Allow the sponge to air dry completely before use.

Its important to note that the sponge may not immediately expand to its full size after removing it from the water. You may need to gently manipulate and stretch the sponge to help it reach its full size.

Here are a few care instructions for this sponge:

1. Rinse the sponge thoroughly with clean water after each use to remove any dirt or debris.
2. Squeeze out excess water from the sponge and allow it to air dry completely before storing.
3. To avoid cross-contamination, use a separate sponge for wheels and tires.
4. Do not use bleach or harsh chemicals to clean the sponge as it may damage the material.
5. Replace the sponge if it becomes excessively worn, torn or discolored.
