Exterior:
OMEGA-Super may be used at a concentration of 1 part OMEGA-Super to 5 to 10 parts of water, depending upon soil  conditions. Spray on and agitate with a soft bristle brush, let stand until all  soils are in suspension, and rinse off  with clear high-pressure water.
Where the aircraft is extremely dirty, especially prop-type aircraft where oils are blown back along the fuselage, mix 1  part OMEGA-Super with 4-10 parts stoddard solvent.
This mixture is excellent for engine nacelles, jet pods, and exhaust tracks.  Additionally, this solution greatly assists the removal of dead paint oxide from snowcaps.

Interiors: Cabin Service:
OMEGA-Super mixed with 1  part to 10 parts water is excellent for removing nicotine stains from the outflow surfaces of air conditioning units, plastics, fabrics, etc. This same mixture leaves stainless steel shining  and spot free.
The best means of application for this purpose is by non-atomizing trigger type spray; wipe off, no rinsing necessary.
