Tips For Hand Grip Exercise Set

To keep your 5-piece hand grip set in good condition for long-term use, follow these care tips:

1. Regular Cleaning
Wipe the plastic components (gripper, finger stretcher) with a damp, soft cloth (avoid harsh cleaners) to remove sweat or dirt after each use. For the foam stress ball, gently hand-wash with mild soap and water, then air-dry completely—do not machine-wash, as it may damage the foam.

2. Lubricate Moving Parts
Every 2–3 months, apply a small amount of light machine oil (or silicone lubricant) to the springs of the adjustable gripper and finger stretcher. This prevents rust (for metal springs) and keeps the components moving smoothly, avoiding stiffness.

3. Store Properly
Keep the set in a cool, dry place (avoid direct sunlight or humid areas like bathrooms) to prevent plastic cracking, spring rust, or foam deterioration. You can store the pieces in a small bag or container to keep them organized and protected from dust.

4. Check for Wear & Tear
Inspect the set weekly: look for loose screws on the gripper, stretched/damaged springs in the finger stretcher, or tears in the foam ball. Replace any worn parts promptly—using damaged components may reduce effectiveness or cause injury.
