Using this Cuisinox oil and vinegar cruet set is a breeze. First, fill the glass cruets with your favorite oil and vinegar through the opening. You can use the pourers to dispense the liquids easily onto your food. When you're done, place the cruets back in the caddy for convenient storage. To keep it in good condition, hand wash the glass cruets and caddy with mild dish soap and warm water. Avoid using abrasive cleaners as they may scratch the glass or steel. Store the set in a cool, dry place when not in use. Also, make sure the pourers are tightly attached to prevent any leaks.
