Abstract
Fluorocarbon/hydrocarbon coupling agents are used in conjunction with highly fluorinated or, alternatively, hydrocarbon carrier liquids to remove refractory soils from solid substrates. To remove hydrocarbon soils, such as oils and greases, the coupling agent is combined with a highly fluorinated carrier liquid and the substrate exposed thereto. To remove fluorocarbon soils, a hydrocarbon carrier is used instead.
