// TECHNICAL PROFILE & FORMULATION SCIENCE

Chemical Purpose & Action

APW Pro Clean is an engineered aqueous detergent developed specifically for automatic rotary parts washers and immersion wash tanks. Formulated with low-foaming surfactants that remain stable under 10+ BAR mechanical spray pressures at 60°C–80°C. Delivers rapid degreasing of aluminium cylinder heads, cast iron blocks, and brass valves while leaving a microscopic corrosion-inhibiting monolayer that protects bare ferrous components from flash rusting for up to 60 days.

Key Technical Advantages:

Non-foaming at high spray pressures above 45°C

Multi-metal compatibility protects aluminium heads and bronze bearings

Provides up to 60 days flash rust protection on bare cast iron inside workshop

Splits free tramp oils to surface for easy disc skimmer removal
