Here's an easy old timer way to check for a stem leak without soapy water. Apply a little spit from a finger over the valve stem hole. Fill the hole with it, and if it bubbles the valve inside of the stem needs to be tightened or maybe replaced (it's usually just loose). Like others have mentioned there is a cheap tool for this, or some stem covers have sharp double prong on the top for this. A sharp pointed needle-nose pliers also works. The valve just screws into the inside of the stem clockwise.
Or better yet stop by a tire shop and they will probably check it for free?
