WD-40 Original Formula, Multi-Use Product with Big-Blast Spray, 18 OZ [6-Pack]

Bottom line: The WD-40 Original Formula ($71.52 on Amazon as of 2026-10-06): Big-Blast wide-area nozzle covers large surfaces fast, unlike the standard straw applicator; main trade-off: wide-area spray pattern wastes product on small screws or tight linkages.

Pros & Cons

Pros

  • ✓ Big-Blast wide-area nozzle covers large surfaces fast, unlike the standard straw applicator
  • ✓ 18 oz cans hold more than the common 12 oz size, cutting refill trips on heavy jobs
  • ✓ Six-pack stocks garage, shed, and truck at once for restoration or repair work
  • ✓ Frees rust-to-metal bonds on seized hardware: hinges, chains, pulleys, rollers, gears

Cons

  • ✗ Wide-area spray pattern wastes product on small screws or tight linkages
  • ✗ Big-Blast nozzle is not a precision straw; no drop-level control
  • ✗ 18 oz aerosol cans are bulky to store and ship as flammable goods
  • ✗ Corrosion shielding is a moisture barrier, not a permanent rustproof coating

SpecPicks Verdict

SpecPicks scored WD-40 Original Formula using a rating × review-volume × price-fit model applied to published specs and reviews across the tools & maintenance category. WD-40's tools & maintenance lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for tools & maintenance: PC towers accumulate significant dust in 3–6 months, so cleaning frequency drives cordless vs. canned-air tradeoff decisions. Match the device's RPM or CFM rating to your case size, and confirm battery runtime covers a full tower cleaning before ordering. Prices and stock are set by the retailer and may have moved since this page was last updated.
