The leak
shows itself.
Spray it where you suspect. The bubbles climb out right at the leak, in seconds. No tub, no rolling the assembly across the shop.
You can't fix
what you can't find.
A slow leak is invisible air leaving an invisible gap. Chasing it by feel burns a bay and earns a comeback.
Spray
Bead, valve, sidewall, TPMS. On the car or off.
Watch
Bubbles rise at the exact point air is leaving.
Find it
The one that's actually leaking. No comeback.
Why your spray bottle of dish soap lies to you
Foams on contact, before any air moves. The leak is just one bubble in a field of suds.
Low-foam. It lies flat until air pushes through, so the only bubbles you see are the ones at the leak.
Where it surfaces a leak
Slow leaks
The one-pound-a-week leak before the comeback.
TPMS & valves
Test the seal in place. No dunk tank around the sensor.
Bead & rim
Corroded bead seats show themselves the second you spray.
Repairs
Confirm the patch held before it leaves the bay.
Built for the tire industry. Cased and ready.
A leak detector engineered for the bay, not borrowed from the dish sink. Spray it, read it, wipe it, next wheel.
Straight talk: yes, it is water and a surfactant, same as every leak detector worth using. The engineering is in the foam control, so it points at the leak instead of burying it.
Watch it surface.
The page already makes the case. This last station gives a supervisor the proof, the shop math, and the link to send without repeating the whole story in three floating boxes.
What is the tank costing?
Put your own tank time, re-checks, and slow-leak volume into the meter. It reports cost exposure, not promised savings.

Bubble Check surfaces the leak at the valve, bead, or wheel. The largest independent tire retailer in the country uses it.
