Penetrating Oil / Multi-Purpose Lubricant

Frees seized fasteners — PB Blaster, Liquid Wrench, Kroil, WD-40 Specialist.

24 products in stockSort by Ranked →

Penetrating oil creeps into rusted, seized threads to free bolts that won't budge — exhaust hangers, brake caliper bracket bolts, lug nuts that haven't moved since the car was new. Spray it on, walk away for 10-15 minutes, hit it again, then try the wrench. Multi-purpose lubricants like the classic blue-and-yellow can also displace water and quiet squeaky hinges, but they're not a long-term lubricant — use white lithium or silicone for that.
