THE PART YOUR WASH CAN’T SEE

Clean paint.
Hidden buildup.

The outside of your truck tells only part of the story. Hollow frame sections can hold material around their internal surfaces and drain holes.

BT gives you a way to direct water into those accessible spaces as part of your wash routine.

FOLLOW THE WATER

Beyond the surface.
Into the rail.

Washing the body and flushing the frame serve different parts of the truck. The cleaner directs water through accessible openings, rather than just over the exterior.

01 / ACCESS

Water goes where you position it.

Mount, flush, and move. Reach depends on your frame’s openings and internal layout.

02 / DRAINAGE

Give loose debris a way out.

Watch the drain openings as water carries loosened material out.

BEFORE YOU HOOK UP

Good questions.
Straight answers.

Will it fit my truck?

You need a suitable steel mounting surface and accessible factory frame openings. Check your vehicle before ordering; not every frame provides the same access.

Do I need a pressure washer?

No. The kit connects to a standard ¾-inch garden hose.

Does it remove or repair existing rust?

It flushes loose debris. It does not repair corrosion or structural damage.

What comes in the single kit?

The magnetic flushing head, connecting hose, soap reservoir, and fittings. Your garden hose is separate.

Do I have to drill or permanently mount anything?

No drilling is required. The head attaches magnetically to a suitable steel surface and can be repositioned.
