DISCUSSION:
Some vehicles may blow fine white flakes from the instrument panel and defrost vents when the climate control fan is turned on. These flakes are residue of sodium silicate, which is used to coat the A/C evaporator to enhance its corrosion protection. If excessive amounts of coating are applied during the manufacturing process, there is a tendency for the extra coating to flake off.
Sodium silicate, found in many household products, is a non allergenic material, and is not linked to any long term health effects. It is an irritant due to its alkaline nature and may cause irritation to the eyes, nose, throat, and moist skin areas.
