3. Cleaning


The main castings are cleaned via a number of chemical processes to remove all oil, paint, rust, and residue. The internal components are hand cleaned in a separate process with separate chemicals to avoid contamination.

All chemicals are water-based in line with our commitment to health and safety and minimising harmful impact to the environment; they are also filtered to ensure any contaminants are removed. The components are then repositioned within the BIN system and transported to a clean environment.
