In this video I mention using dish soap in a spray bottle to find the leak. What you want to use is well diluted dish soap using water and dish soap. Maybe 50/50 solution. Once you mix the solution in a bottle, make sure the solution is diluted and the bubbles have settled in the spray bottle before using. You can also try pouring the deluded soap onto a small rag or sponge and squeezing that over the area you're trying to inspect for leaks.
