I use a Ninja Master Prep blender to mix protein powder or Soylent with water. Is there a way to clean it very quickly? The blades are super sharp and I'd rather avoid having to scrub bits of powder that get stuck on them.

Ideally, is there something edible to throw in the mix, that would prevent powders from adhering to the blades or the blender in the first place? Some sort of oil perhaps?

Since I use the blender several times a day, I'd rather not run a dishwasher cycle.

The easiest way to clean a blender is to use the blender to clean itself. As you said a dishwasher cycle is pretty time consuming and not optimal if you use the blender several times a day. So turning the blender into a "dishwasher" is the solution.

I couldn't think of anything, that would prevent powders from adhering to the blender. But here is the solution if they already are sticking there.

What you'll need:

  • some hot water (tap water is fine)
  • dishwashing liquid
  • (optional) half a lemon (white vinegar is an alternative)

Steps to take:

  1. Fill the blender halfway with hot water.
  2. Add one or two drops of dishwashing liquid. If you have half a lemon this is the moment to add it. You can chop it coarsely.
  3. Turn on the blender and let it run on Low for about 30 seconds up to a minute (depending on the power and dirtiness of your blender).
  4. Pour out the soapy water.
  5. Rinse out the blender thoroughly with more hot water.
  6. Finished! Place upside down to air dry or use it right away
