Big blue=big results!
Say goodbye to the soapy water trick, big blue is the RIGHT tool for the job! Sticks where itโs sprayed and makes very clear and visible bubbles. Rinses right off when done, no mess no stress. Great experience so far in the automotive air conditioning sector!

Easy to find leaks
Second time buying this product. Works really well for any type of air or gas leak. Just make sure you clean up after it. It leaves a slippery film on whatever you use it on. Very easy to find the leak tho.

Outstanding product
Great product. Shipping issue with leaking bottle, a cardboard mess; seems like a simple plastic bag would be helpful.

Canโt find your leak? Give this a try!
This leak soap is very thick, sticks where you squirt it. Finds super tiny pin holes in HVAC cores. Highly recommend this. Using it to find automotive ac leak, spraying all connection joints, service ports, receiver dryer /accumulator and condenser. I used about 1/2 the bottle to find the leak. Mind you, I was using it, not conserving any.
