What Kroil products are used in automotive repair shops?
Automotive repair professionals most commonly use Kroil Original Penetrant (liquid) and Aerokroil (aerosol) for freeing rusted exhaust bolts, manifold studs, brake caliper slide pins, suspension fasteners, lug nuts, and corroded battery terminals. Aerokroil is preferred for precision applications on overhead components and tight engine bay spaces. Kroil Original liquid is used for soaking larger assemblies or heavily corroded components. Auto restoration shops frequently use Kroil on vehicles that have been in storage for years, where comprehensive corrosion on fasteners throughout the vehicle makes a long-dwell penetrant essential. Additional products of value to auto shops include Kreen all-in-one gas & oil treatment, Floway solvent, Exrust industrial strength rust remover and Kroil Shield corrosion inhibitor.
Looks like Kroil products have new packaging. Have the formulas changed?
Thanks for noticing our great new look! Kroil products have indeed received a facelift, but rest assured, the same great products are still inside the cans. The formulas haven’t changed.
