Cleaning your Truffle mini train case is a breeze. The biodegradable TPU used in our bags is designed for easy maintenance. Over time, the TPU might develop some cloudiness, but refreshing it is simple. For routine cleaning, use your preferred essential oil with a soft cloth. For tougher jobs, we recommend Novus Plastic Clean & Shine #1 and #2 for cleaning and polishing plastic. See our Care & Cleaning Guide for more cleaning tips.
