Daily Cleaning Tips for Optimal Performance
After each use, it’s important to clean the Ninja SLUSHi Max XXL thoroughly to prevent residue buildup and ensure fresh-tasting drinks every time. Remove the blending jar and wash it with warm, soapy water, paying special attention to the blades. Wipe down the exterior with a damp cloth to remove any spills or splashes.
