How to Find a Pin Hole in an Air Mattress

Air mattresses are common sleeping furniture for campers.

A pin hole in an air mattress can soon cause it to sag, leading to an uncomfortable night's sleep. Pin holes are small and difficult to find by the usual methods of listening for the sound of escaping air, or holding a sheet over the mattress and looking for where it rises up. To find a pin hole in an air mattress, you must use bubble-blowing soap.

Things You'll Need

• Bubble blowing solution
• Sponge
• Water-proof marker

Instructions

1. Remove all the sheets and blankets from the air mattress.

2. Dampen a sponge with bubble-blowing soap and wipe down the entire surface of the air mattress, starting with the seams, where leaks are most common. Wipe the mattress one stroke at a time, and watch carefully for any bubbles that form in the soap. Wet the sponge when it dries out.

3. Circle the pinhole with a water-proof marker when you find it. A pin hole will produce bubbles when you pass over it with the soapy solution.
