Flash rust often occurs when freshly cleaned metal parts are exposed to moisture or humidity before a corrosion inhibitor is applied. To prevent flash rust after washing, ZERUST® offers a comprehensive range of part washing fluids with integrated rust inhibitors under the AxxaWash™ series. These formulations are engineered to clean effectively while stopping flash rust formation during the critical transition from washing to drying.
The AxxaWash™ KF-123, KF-124, and KMS-220 products are low- to very low-foaming, mildly alkaline or near-neutral cleaners that remove light to heavy hydrocarbon soils, including machining fluids, oils, and greases. Each product leaves a light, corrosion-inhibiting layer on metal surfaces to prevent flash rusting during handling, staging, or storage. This makes them ideal for manufacturers seeking reliable ways to prevent flash rust after washing without adding extra process steps.
Depending on the type of soil being removed, the metal composition, and the desired protection duration, ZERUST® offers an AxxaWash™ solution tailored to meet specific cleaning and corrosion prevention requirements. For guidance on selecting the best solution for your needs, you can contact ZERUST®/EXCOR® to speak with a technical service representative.
