Balanced Cleaning Chemistry
Instead of relying on heavy alkalinity alone, FEYNLAB APC uses a two-stage approach.
Citrus oils help break down organic contamination, while a Smart Surfactant Package lifts and carries away inorganic soils. The formula runs at roughly half the alkalinity of many competing APCs, which helps maintain material compatibility when used correctly.
The result is predictable cleaning performance without the harsh feel common to stronger APCs.
