The removable base allows direct rinsing under the tap or using the electric self-clean function by adding warm soapy water and switching the unit on for a short cycle. 🧼

Usage Recommendations

For best results pre-mix powders with a small amount of liquid before filling the bottle to reduce clumping, especially with thicker formulations such as mass-gainer mixes. When using fruit or vegetables include smaller pieces to avoid obstructing the mixer and to ensure a uniform blend. The removable base makes hand rinsing straightforward, and periodic disassembly of the lid seal helps prevent odours and residue build-up. ⚠️

Consider that the motorised mixer is powered by a modest internal battery, so if you need dozens of shakes a day you may need to recharge more often than with a manual shaker. Also, while Tritan resists impact and heat better than some plastics, the manufacturer’s guidance should be followed regarding exposure to very hot liquids.
