Find out why you should mix WD40 with sand

This article shows a home experiment where WD-40 is mixed with sand to create an abrasive mixture effective against rust, old paint or even to give a matte finish on metals.

By combining the lubricating properties of WD-40 with the frictional power of sand, a compound that cleans and polishes simultaneously is achieved.

You can then follow the procedure in the following video from the Creation Tips channel:

Materials Needed

1. WD-40 – A multi-purpose lubricant and penetrant.
2. Fine, dry sand – Preferably clean, free of moisture and impurities.
3. Sturdy container – Any strong metal or plastic canister that allows for spill-free mixing.
4. Nitrile gloves – Protect your hands from direct contact with chemicals.
5. Safety glasses – Prevent splashes in the eyes.
6. Wire brush or abrasive sponge – To apply and rub the mixture on surfaces.
7. Clean rag or old towel – To wipe off excess and dry.

Steps to prepare and apply the mixture

1. Protection first
   Put on gloves and goggles before you start.
2. Mix
   Pour WD-40 into the container (enough to moisten the sand). Add sand slowly and mix until you get a pasty texture, not too runny to avoid dripping.
3. Application
   Apply the paste with a brush or sponge. Use consistent circular or rubbing motions.
4. Allow on
   Wait about 5 minutes for the WD-40 to penetrate rust or paint.
5. Rub
   Use moderate pressure until you notice that the surface improves.
6. Clean
   Remove residue with a clean cloth. If there are still remains, repeat application.
7. Drying and sealing (optional)
   Dry the surface thoroughly and apply a sealant or protective coat if desired.

Additional Tips

• Pre-test: Test a small, inconspicuous area to verify that there is no damage.
• Type of sand: Beach sand usually has salts; prefer clean construction litter or 100% cat litter.
• Polishing alternative: If you’re looking for shine instead of matte, soften the sand ratio.
• Non-aggressive: This method is less abrasive than sanding, ideal for delicate surfaces such as tool restoration or old metal parts.
• Environmental waste: Dispose of the used mixture in an impermeable container, as it may contain particles and fuels, which should not leach into soil or water.
• Ventilation: WD-40 has volatile solvents; Use this method in a well-ventilated area or outdoors.

IMPORTANT: The mixture of WD-40 with sand offers a simple and effective solution for cleaning, polishing or restoring metal surfaces. It combines the chemical penetration of the lubricant with the mechanical action of the sand, saving time and effort. With the right precautions, you can extend the life of your tools or give old parts a new shine.
