If you’re going to use your blender for commercial use, perhaps in your smoothie bar, it’s important to select a model made of the most durable materials. Stainless steel is easy to clean, and will possibly handle foods of all temperatures. So, you’d be looking at a base and blades that are made of stainless steel.
When it comes to the jug, you’re looking for something made of tempered glass. Glass is BPA free which means there is no risk of plastic chemicals contaminating the food. Glass also doesn’t absorb food stains and flavors like plastic might. Ensure that you select a model that can handle commercial use. Refer to our “Features to consider” section in our buyers guide for a more detailed idea of what you should look out for.
