Every woman has had this problem at one time or another—the knotted necklace chain. Here are two tips for untangling the tangled mess.
First, try sprinkling the knot with baby powder. This should help loosen the knot. Then you can use a pin or needle to finish unknotting the chain.
If the baby powder doesn’t work for you, try applying a bit of olive oil or mineral oil to your fingers, then rubbing your fingers over the knot. Clean the oil off your fingers, then try unknotting with a pin or needle.
Make sure you wash the chain with soap and water afterwards and dry thoroughly with a lint-free cloth.
