The small elements are removed and sun dried before cleaning. Cleaning car elements is not easy. The strong, chemical solvent is damaging for the hands. For the larger elements, the engine is warmed to let the grease loosen up a bit. The loosening of grease emits a lot of damaging chemical compounds. The solvent which is utilised as elements cleaner, when washed with water, releases gunk and grease which are again toxic. Now, when the engine begins to dry off the water, it emits toxic fumes again.
