We recommend that after each use you blend water with a drop of soap to clean your blender. Rinse with plain water and you are good to go again! It is very important to clean your BlendnGo after each use to avoid odors developing. It is also best to store your BlendnGo with the lid off to avoid any odors. To give your BlendnGo a deep clean you can take all pieces apart as well as the seal rings. Always make sure to securely re insert the seals before blending again.
