## Summary description

Wd-40 penetrant spray (WD-40 103) in a 400 ml aerosol delivers a multi-purpose lubricant and rust-penetrating formula. Designed to loosen seized screws and bolts, displace moisture, protect metal surfaces from corrosion, and reduce friction. Suitable for automotive, household and workshop maintenance tasks where freeing corroded parts and light lubrication are needed.

## Long description

Wd-40 penetrant spray (WD-40 103) in a 400 ml aerosol is a multi-purpose lubricant and rust penetrant formulated to free seized screws, bolts and other corroded fasteners. The aerosol delivers a thin, low-viscosity fluid that displaces moisture, reduces friction and provides short-term protection against corrosion on metal surfaces. This spray is suitable for routine maintenance in automotive, household and workshop environments where access to tight or rusted parts requires a fast-penetrating solution.
Advantages
The penetrant spray combines rapid penetration with light lubrication, allowing stuck parts to be loosened without extensive force or disassembly. Its moisture-displacing action helps prevent electrical contact faults and inhibits further corrosion on treated surfaces. The aerosol format with a precision nozzle enables targeted application in confined areas, while the low-residue formulation leaves metal surfaces ready for subsequent mechanical work or longer-term lubricants.
Suitable for
 Freeing seized screws, nuts and bolts on vehicles and machinery
 Lubricating hinges, locks and moving metal parts around the home
 Displacing moisture from electrical contacts and connectors
 Preparing corroded fasteners for removal during repairs and maintenance
Key specifications
 Volume: 400 ml aerosol
 Function: rust penetration and light lubrication
 Application: targeted spray for tight or corroded parts
 Residue: low-residue formulation suitable for subsequent mechanical work
 Protection: short-term corrosion protection after application
How to use
Shake the can well before use. Hold the aerosol upright and apply a short spray directly onto the corroded or seized area, keeping a safe distance as indicated on the label. Allow the product to penetrate for a few minutes; repeat application if necessary. After loosening, wipe away excess residue and proceed with removal or mechanical adjustment. Use in a well-ventilated area and follow any safety instructions on the product packaging.
Usage recommendations
For best results, apply the spray in short bursts and allow time for penetration before attempting to turn or move the fastener. Protect surrounding painted or plastic surfaces from overspray and test compatibility on sensitive materials. After freeing parts, consider applying a heavier-duty lubricant or anti-corrosion treatment for long-term protection when appropriate.
