When cleaning your concrete mixers, make sure to always do it when the cement is still wet, as this means you don’t need to use any chemicals. Instead, fill the mixer around halfway with water, add in two shovels of gravel and turn on the mixer to allow it to spin. This will remove the cement from the bottom and sides of the mixer, then tilt the machine up until the gravel mixture reaches towards the top to clean the machinery fully. Once all of the concrete is removed from the mixer, drain the water and remove the gravel. Pressure wash any remaining residue from the inside and outside of the cement mixer and then allow it to dry fully before putting back into storage.
