Terp Wipes are thick single-use cotton wipes perfect for cleaning our quartz bangers as well as any of our glass pieces. The Ethyl alcohol solution combined with the thickness of the wipes makes them far more absorbent than regular alcohol wipes. Terp Wipes are safe for use with glass, quartz, metal, drip tips and are safe for hands.Ethyl alcohol is grain-based, non-toxic and food safe. It also evaporates more slowly than Isopropyl Alcohol (iso), allowing for more time to use the wipe after it's opened.Please be careful to not touch hot quartz or glass pieces directly with these wipes. Allow some time for things to cool down!What's in the box:70 individually packaged swabs3 cleaning sticksSize / Material: 2.5" x 2.5" Cotton WipesCleaning Solution: 75% ethyl alcohol / 25% distilled water
