Modern de-icers such as our Prestone De-Icer aren’t bad for your car when used properly. You can safely and effectively use the sprays and aerosols to remove ice without worrying that they’re causing damage, corrosion or any other issues.
That being said, it’s not advisable to use de-icer anywhere other than the car windows and glass areas. Avoid using your de-icer on a car’s interior because the chemicals can cause damage to fixtures and upholstery. We also strongly advise against using it in or around the engine bay since this could cause irreversible damage to the major components of the car.
