KNOCK OUT effectively removes industrial fallout such as rail dust and smokestack fly ash. When used with care, KNOCK OUT dissolves the minute iron particles which are embedded in painted surfaces. This product is a surface cleaner that may be used in the process of automotive refinishing. KNOCK OUT is formulated with mild organic acids, which are safe on glass and paint.

Introduction to Detailer Training Series Course

When detailing a vehicle, producing results correctly, safely, and effectively is crucial, especially in the professional detailing industry.


(1) Fallout. Refers to minute iron particles, sometimes hot, of rail dust and smoke stack fly ash caused by friction between train wheels and track. Fallout takes effect to the vehicle either during transportation by rail car or truck, or when stationary in a heavily contaminated area. (2) Brake dust. Composed of metallic iron particles, brake dust is a dark-coloured residue caused by the grinding of iron and brake pads, and takes place when braking occurs. (3) Metal oxides. When chemicals in a vehicle’s exterior painted surface break down, the underlying metal is exposed to oxygen and causes metal oxides.

Both fallout and brake dust produce minute metallic iron particles that become embedded in the vehicle’s exterior painted surface and form a bond with the metallic substrate underneath. Metal oxides, formed when the vehicle’s exterior painted surface breaks down, begins to corrode.

Fallout, brake dust, and metal oxides typically rust and discolour the paint, affect the smooth surface texture, and are easily noticed on vehicles with white paint.

Removal of these metallic iron particles is accomplished by using KNOCK OUT. KNOCK OUT is a cleaner formulated using organic acids that dissolve the metallic particles, enabling complete, safe removal. The YELLOW NANO BUFF WASH MITT, BLUE NANO BUFF WASH MITT, GREY CLAY BAR, and PURPLE CLAY BAR are also effective at removing surface contaminants; however, are not recommended for medium to heavy applications, where metallic iron particles are embedded into the painted surfaces.

The minute metallic iron particles, embedded into a vehicle’s exterior painted surface, caused from fallout, brake dust, or metal oxides, form a bond with the metallic substrate underneath. Special organic acids are required to effectively dissolve the metallic particles to enable a complete and safe removal from the vehicle’s exterior painted surface. KNOCK OUT contains the organic acids required, and is designed specifically for this type of application.

Direction Of Use

  1. Wet the painted area of application with cool water.
  2. Spray undiluted KNOCK OUT on the painted area of application.
  3. Allow KNOCK OUT to crystallize on the painted surface, approximately 5 to 10 minutes, depending on relative humidity.
  4. Rinse the area thoroughly with a high-pressure washer.
  5. For stubborn particles, retreat areas, repeating steps 2 to 4.
  6. Wash the vehicle using a Vehicle Wash Soap, to allow for final neutralization and particle removal.
Precautions: Apply to a cool surface only. Do not apply in direct sunlight. Do not mix with other chemicals.
