PB Blaster

PB Blaster is the trade name for The B'laster Corporation's line of penetrating catalysts and lubricants, made in Cleveland, Ohio since 1957. The flagship 16-PB aerosol is the most widely recognized penetrating oil in the United States, ubiquitous in automotive shops, hardware stores, and garages across the country.

The brand built its reputation on one thing: freeing rusted and seized fasteners. That singular focus — plus decades of word-of-mouth from mechanics who swear by it — has made PB Blaster the default recommendation on automotive forums and in dealership service bays. Blaster LLC also makes White Lithium Grease, Silicone Lubricant, and several other specialty products under the Blaster brand.
