I wouldn't use this stuff if it contains caustic soda / sodium hydroxide / NaOH. This will dull aluminum, not good for steel, not sure what it'll do with rubber, will burn your eyes and skin, and burn your lungs if you inhale the aerosol. I use mineral spirits. Many here swear by detergent-based cleaners like 'simple green'. Mineral spirits are flammable so use outdoors or with good ventilation & away from sparks & flame.
