When requesting cylinder refills, if you are able to, please could you help us keep cylinders clean before returning them?

• Using a clean cloth that has been dipped into clean soapy water (washing up liquid mixed with tap water) and wrung out so it not soaking wet
• Wipe the cylinder from the top moving downwards towards the bottom
• Please avoid water entering the silver metal filling port of the cylinder
• Dry the cylinder with a clean paper towel such as kitchen towel

We also decontaminate the cylinders when we refill them, but any additional cleaning is always helpful, thank you.
