Used this stuff to clean up old calipers, tried on brake dust on car wheels. Works so good. Apparently mag cleaner sprays etc arent allowed any acid in their formulas, this still doese at $5 bottle, not 25 the car products cost. Many uses for 14 i reckon. https://www.colgatepalmolive.com.au/brands/ajax/ajax-professional/ajax-professional-bathroom

For caliper cleaning tried WD40 with old toothbrush. Then I remembered the ultrasound bathtub I had bought and become disillusioned with. After 5 min the calipers came out immaculate!
