Care & Cleaning
Wipe vinyl surfaces with a mixture of water and tea tree oil, a natural
disinfectant. Add 5 ml or 1 tsp of tea tree oil to a 1L or 1qt spray
bottle of water. A mixture of mild soap and water may be used to
remove more persistent dirt. Ensure cleaner does not leave an oily
residue, or make surfaces slippery. Clean all metal surface areas
as required, using a soft cloth and gentle cleaner.
If necessary, hinges can be cleaned with a cloth and window cleaner,
(spray cleaner onto the cloth first, not directly on the equipment).
It is not necessary to lubricate the hinges.
