Gold is a very versatile metal and in most cases can be worn on a
daily basis. However, there are some "dos" and "don'ts" when it comes
to gold.

"Do" take your gold jewelry off when you take a bath or clean your
house. Even though soap will not hurt your gold jewelry is will leave
a fine scum on it which will make it appear dull. This film can be
cleaned off, but removing your gold jewelry will be a lot easier!

"Don't" wear your gold jewelry, especially white gold, if you plan to
go swimming or get into that hot tub that contains chlorine. Chlorine
can permanently change the color of your gold. It can turn white gold
yellow. Remember to also be careful when using those household
products containing chlorine bleach.

"Do" keep your gold jewelry clean. You can purchase a commercial
cleaner or you can clean your gold by soaking in a solutions of one
part ammonia and six parts water. Soak for about 1 minute then use a
small soft brush, like a toothbrush to scrub lightly. Rinse in warm
water and dry with a soft cloth or chamois. (Soaking in a glass of
water with a denture tablet works well also.)

"Don't" use harsh or abrasive cleaning solutions on your gold jewelry.
Gold can be fairly soft and may get scratched.

"Do" take your gold jewelry off when taking antibiotics. Strange as it
seems some prescription drugs can alter the chemical properties of
your sweat and cause tarnishing.

Got a knot in your gold necklace, gold chain, or gold bracelet?

Here's a trick - lay your gold necklace, gold chain, gold bracelet on
a plate or piece of wax paper. Apply a drop of household or salad oil
on the knot and use two straight pins to pull the knot out. Need to
get the oil off? Dip your gold jewelry in some rubbing alcohol, rinse
with warm water, and dry with a soft cloth or tissue.
