Lay the necklace flat on a smooth surface, open the clasp gently and leave slack near the knot.
Use two pins or needles to ease loops apart slowly. Keep the chain supported and avoid pulling the ends.
Oil is only for suitable plain metal. Never use it on pearls, gemstones or plated costume pieces.
Wipe off any oil gently after loosening. Ask a jeweler about fine chains, damage or a stubborn knot.
Store chains fastened and separate, with room to lie flat instead of crossing other pieces.
