How do I clean them?

Cleaning is easy. Simply take a wet cloth and wipe them down. You do not want to use any chemicals or cleaning agents as those can damage the latex and decrease their durability.

What are the types of hand grip strengtheners?

There are 3 types of hand grip strengtheners: spring-based, coil, and articulated. Spring-based strengtheners are bound by a spring and have handles separated by a hinge, and the difficulty of the squeeze is determined by both the tension and length of the spring. Coil strengtheners are built around a coil. Every time you grip, it tightens the coil. Articulated strengtheners allow you to squeeze each finger individually by using a series of springs.
