Gets your vehicle... clean, clean
Connect your hose. Load up the soap dispenser. Snap it under your chassis and start blasting away the mess.
Make your chassis shine
Our simple, yet powerful design will rip the grime off your chassis in minutes. You can have the BT chassis flusher setup from box to sprayer in just minutes. It's the easiest and most effective way to get your vehicle clean, clean, after a fun day outdoors.
What Your Car Wash Doesn't Touch
Your chassis is rusting from the inside out. Road salt, dirt, and grime hide where sprayers can't reach.
Snaps On Magnetically
Locks onto your frame rails in seconds. No drilling, no permanent mounts, no tools needed.
Soap Dispenser Built-In
Fill it with degreaser or car wash soap. High-pressure water mixes and flushes out hidden grime.
Blasts Inside Frame Rails
Multi-directional jets reach the spots that cause rust — inside your frame where water hides.
Works With Your Hose
Connects to any standard garden hose. Setup takes 2 minutes, cleaning takes 5.
The Hidden Damage You Can't See
Every drive through rain, salt, or dirt deposits corrosive material inside your frame rails. Car washes only clean what they can see.
Why the BT Chassis Flusher is Essential:
-
Prevents Frame Rust — Flushes out salt and moisture trapped inside hollow frame rails.
-
Reaches Where Car Washes Can't — Gets inside the frame, not just the outside surface.
-
Protects Your Investment — Frame rot destroys resale value. Prevention costs pennies compared to repairs.
-
5-Minute Maintenance — Quick rinse after winter drives or muddy roads keeps your frame protected.
