TAIPAN is formulated to penetrate air conditioner evaporator/condenser coils and fins to remove all types of grease and grime. The spray allows product to be dispersed deep into the fins of the coil. Upon contact with the surface of the coil, this product begins to react and flush soil to the surface. TAIPAN needs to be rinsed if applied in place to a functioning unit that produces moisture. The moisture produced will rinse product from contacted surfaces. It is necessary to rinse units that have been removed for repairs or do not produce moisture during operation.
