A powerful, thick, clinging foam which removes dirt, lint and grease from air conditioner and heater coils. The lightweight, portable aerosol canister features a strong, directional spray which helps force foam into coil air spaces. No rinsing necessary on evaporator coils or any other surface where condensation causes a rinsing action. Water-based foam creates no harsh vapors and leaves a fresh natural scent. The natural ingredients used are formulated to remove stains and odors associated with mold and fungus.
