Metal statuettes, figurines, candlesticks and ornaments brighten up a living room, study or a shelf of keepsakes. But cast iron and steel pieces rust over time, especially near a window, in a bathroom or kitchen, or in a house left unheated in winter.
Do not ignore orange bloom: it spreads gradually and can permanently spoil fine relief. First identify the metal. Bronze, brass and copper do not rust; they develop a dark or green patina that is often valued and left alone. This method is for iron, cast iron and steel pieces.
What you will need
- soft dry cotton cloth or a dusting brush
- WD-40 Multi-Use
- soft brass brush or an old toothbrush
- fine abrasive paper (only if needed)
- cotton buds for relief detail
Important: Do not use a brush or abrasive paper on painted, gilded, silver-plated or lacquered figurines: you may strip the finish. Test the product on a hidden spot on the back first. Valuable or antique pieces are best left to a restorer.
Step 1
Dust the figurine
Remove dust with a soft cloth or brush, especially from recesses in the relief. If the piece is very dirty, wipe it with a damp cloth and let it dry completely.
A clean surface lets the product reach the rust directly.
Step 2
Apply WD-40 to the rust
Carefully apply WD-40 Multi-Use to the affected areas so they are fully covered. More product does not mean better results; a thin coat is enough.
For fine relief and awkward spots, apply it through the thin straw of WD-40 Smart Straw or dab it on with a cotton bud.
Step 3
Wait 10 minutes
Leave the figurine for 10 minutes. In that time the product works between the rust particles and loosens their grip on the metal.
Stand the piece on a cloth so excess does not reach the furniture.
Step 4
Remove the rust with a soft brush
Go over the treated area with light strokes of the brush. The softened rust comes off easily while the relief stays intact. Use a toothbrush for small details.
If not everything comes off first time, repeat the treatment rather than scrubbing harder.
Step 5
Finish off and polish
Stubborn marks on smooth, unpainted areas can be lightly sanded with fine paper. Then wipe the figurine thoroughly with a clean dry cloth.
Leave a barely visible film of lubricant on the metal: it protects against damp and restores an even sheen.
Tip: Do not stand iron figurines on a window sill with condensation and do not wash them under the tap. Regular wiping with a dry cloth adds years to their life.
What next
Check metal ornaments every few months and renew the protective film, especially in autumn and winter when the home is damper. For a small collection, a pocket WD-40 100 ml is ideal.
These uses come from the experience of WD-40 users in many countries. Always follow the instructions and warnings on the product label.
