Using the Pipedream Products Icicles No. 86 Glass Massager is easy. For solo use, just hold it by the 2 - inch base and start exploring. If you're using it with a harness, attach it securely to the harness. When using the suction base, find a smooth surface, press the base firmly to create a seal. Make sure the surface is clean and dry for the best suction. After use, wash the massager with warm water and mild soap. Since it's waterproof, you can even clean it in the shower. Store it in a cool, dry place away from direct sunlight. Avoid using harsh chemicals or abrasive cleaners as they may damage the glass and silicone parts.
