# Cleaning and Care The Senstream Research Ring and sizing shims are made with biocompatible engineering resin. We recommend wiping down the ring with Sterile Alcohol Prep Pads before each session. This manages the amount of fluid used to clean the ring and prevents a delay in operation due to excess fluid shorting between the electrodes. We also recommended that each participant wash their hands before and after each session. Do not submerge the ring in any cleaning fluid or water. If you do accidentally immerse the ring in fluid do not put the ring on a finger or apply the charging cable for at least 24 hours. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
