How to clean dry cement from a mixer

According to the Health and Safety Executive, some workers have developed hand-arm vibration syndrome after using hand-held power tools to remove hardened concrete from cement mixers. Suitable cleaning chemicals can help prevent this occupational disease.

Here is our guide on effectively and safely removing dry cement from a mixer:

  1. Make sure to put on the correct health & safety/PPE equipment, e.g. goggles and gloves to prevent skin contact
  2. Whilst the mixer is off, fill one third of the drum with water
  3. Using a chisel, lightly tap the outside of the cement mixer to encourage any residual cement that is stuck to the sides to loosen
  4. Add concrete cement mixer cleaner to the drum – this is dependent on the substrate you’re trying to remove, always read the manufacturer’s advice for quantity information. You can slightly tilt the drum to make sure that the entire inside is coated with the diluted chemical solution
  5. Turn the cement mixer on, letting it turn long enough for the cement mixer cleaner to loosen the hard, dry cement residue
  6. With the cement mixer off, use a chisel or shovel to scrape away any leftover cement that the cement mixer cleaner wasn’t able to remove
  7. Use a pressure washer to rinse inside of the drum, ensuring to clean the inside thoroughly
  8. Make sure that the cement mixer is completely chemical and debris free and fully dry before utilising it as normal

How to clean wet cement from a mixer

  1. Fill the mixer with a reasonable amount of water
  2. Add in a couple shovels full of gravel
  3. Turn the mixer on and allow it to spin. The gravel will move with the water and scrape the cement off the sides
  4. Tilt the machine so that the gravelly mixture reaches all the way to the edges
  5. Once the cement has been removed, drain the water and gravel in an appropriate place
  6. Use a pressure washer to remove any remaining residue from the interior and exterior of the machine
  7. Let everything dry off before storing

How to choose a cement mixer cleaner

Traditionally, hydrochloric acid was the primary solution to use when cleaning cement mixers – but this has proved to be extremely hazardous, to the point of being banned from construction sites altogether. It has a dangerous history of causing respiratory inflammation and gradually corroding construction equipment – Chela sought to offer a safe, clean solution to cement mixer cleaning.
