Maltby Chemical Penetrant is a high-strength, commercial-grade formula engineered to attack severe rust, creep into microscopic tolerances, and free seized metal components fast. Compounded with Maltby’s exclusive R-90 additive blend, it breaks down tough surface oxidation, displaces moisture, and leaves a lasting protective barrier against ongoing friction and corrosion.

🔑 Key Benefits

Fast-Acting Rust Dissolution: Penetrates deep into galled threads, frozen joints, and oxidized metal bonds.
Corrosion Inhibitor & Lubricant: Eliminates squeaks, reduces friction, and protects bare metal surfaces.
Moisture Displacement: Drives out trapped water and condensation from metal assemblies. (Note: Not intended for use on electrical contact switches, porous plastics, or sensitive paint finishes).

🔩 Common Applications & Uses

Automotive & Heavy Equipment: Nuts & bolts, exhaust manifolds & mufflers, brake cylinder honing, engine disassembly, chassis suspension, battery brackets & cables, heat risers.
Farm, Industrial & Manufacturing: Cables & linkages, tractors, mowers, yard equipment, trailers, heavy machinery maintenance.
Marine & Outdoor Power: Outboards, boat hardware, rods & reels, guns & rifles, rusty hardware exposed to weather or salt air.
Shop & General Household: Locks, hinges, sliding doors & screens, tools, sewing machines.
