Foaminator is the only true time delayed-foaming coil cleaner and that delay is the whole point. During application, the liquid penetrates deeper and doesn’t react for 60-90 seconds, seeping into every crack, crevice, and saturating all the contaminants in the core of the coils. Once that reaction starts, a thick and dense foam expands from the inside out with massive force, pushing dirt, grease and grim outward from the center instead of trying to wash it through. The sodium hydroxide base saponifies grease and the surfactant blend emulsifies other contaminants with ease. The chemistry behind that delay also keeps the cleaner as a liquid rope when sprayed instead of a mist, ensuring the cleaner ends up on the coil where you want it.
