Make your own leak detector solution in a spray bottle to pinpoint leaks.

There are many uses for a leak detector solution around the house. Whether you're trying to find the source of a slow leak in a car tire or find the hole that's causing your children's bouncy house to deflate, a leak detector solution can pinpoint the problem quickly. A leak detector solution can also be used proactively to check your hoses when you start your barbecue grill up for the first time in the spring to be sure there are no cracks that can lead to gas leaks.

Step 1

Combine 1 cup water with 1 cup liquid dish soap in a spray bottle and swirl gently to mix.

Step 2

Set the spray bottle to a direct stream spray.

Step 3

Spray the item you are checking for leaks thoroughly with the homemade leak detector solution. The air or gas leaking out will cause bubbles to form at the leak site.


If you need to check a large area for a leak, or you don't have a spray bottle on hand, mix equal parts liquid dish soap with water in a bowl or bucket and apply it to the object you are testing for leaks with a sponge.


Do not shake the spray bottle to combine the soap and the water, or you will end up with bubbles instead of a liquid solution.
