Wurth A/C & Heating Treatment is a powerful weapon against the odors that contaminate your vehicle's air conditioning system. Wurth A/C & Heating Treatment eliminates mildew, moisture, bacteria, and mineral deposits that emit unctuous odors. Despite its cleaning prowess, this formula is safe on vinyl and plastic so there is no chance of material damage. Wurth A/C & Heating Treatment has a fresh lemon scent but does not mask foul smells; it removes them at their source. Comes in 6oz can.
