- Restores Performance - Removes gelled fuel, tarnish, oxide and debris from bowels and jets. Gelled fuel from standing or over-wintering vehicles has a dramatic effect on fuel system and power output, cleaning your carburettor with ultrasonic fluid restores power and fuel efficiency by unblocking jets and float chambers allowing proper injection and fuel to air ratio.
- Powerful performance great for restoration & maintenance dilute Up to 1- 10 with hot water. Use multiple times for great value.
- Ideally suited to carburettor cleaning - safely restores manifolds, carburettors and most machine parts. Alcohol based surfactants and buffering agents combine to impact debris with over 4000c implosions produced by ultrasonic sound waves to break down surface contamination. The grime is held in solution leaving the item clean and decontaminated.
- Aluminium safe, will not darken parts. Use on Steel, Brass, Tin, Zinc, Aluminium, Copper, Ceramic, Plastic, Rubber and glass. Unlike acid-based cleaners our solution will not attack aluminium to darken the surface instead it is compatible and leave a good clean finish.
