Yes. ZERUST® offers several non-staining rust preventatives for aluminum and copper. These products protect non-ferrous metals, multimetal assemblies, and steel without causing discoloration, tarnish, or surface spotting.
When protecting aluminum or copper parts, especially in multimetal assemblies, it is critical to select a corrosion preventative that forms a clear, non-staining protective layer. The product must also remain compatible with the alloy and surface finish, while avoiding residue that could interfere with downstream operations such as welding, painting, soldering, or assembly.
Non-staining rust preventatives for aluminum and copper using water-based technology
ZERUST® Axxatec™ water-based corrosion inhibitors protect metal components when appearance and cleanliness are critical.
ZERUST® Axxatec™ 48C is a water-based, non-staining corrosion inhibitor designed specifically for aluminum and yellow metals while also protecting ferrous substrates. Additionally, it dries to a clear, residue-free film, making it ideal for storage and shipment where surface appearance must remain unchanged.
ZERUST® Axxatec™ DA-40AL provides dual-action cleaning and corrosion protection for aluminum and multimetal components. Furthermore, this solution supports applications that require surface preparation and short-term protection in a single step.
ZERUST® Axxatec™ 80C offers a clear, non-staining protective film compatible with aluminum, copper, ferrous metals, and yellow metals. It is often selected for components that must remain clean and visually pristine during processing, storage, or shipment.

Non-staining rust preventatives for aluminum and copper using oil-based technology
Several ZERUST® Axxanol™ rust preventatives also provide effective protection without leaving dark, oily, or staining residues on aluminum or copper surfaces.
ZERUST® Axxanol™ A35CD-32 forms a dry-to-touch, clear protective film that resists staining and is easy to remove. Furthermore, manufacturers commonly use it for precision-machined parts and multimetal components that require a clean surface finish.
ZERUST® Axxanol™ 718-ESS is a thin, water-displacing, non-hardening electrical corrosion inhibitor. Additionally, it protects aluminum and copper components without heavy buildup, making it suitable for sensitive assemblies and electrical applications.
These products resist staining, clean easily, and preserve surface appearance while delivering reliable corrosion protection.

Verifying compatibility for non-staining rust preventatives
Although ZERUST® products are designed to be non-staining, appearance can vary based on alloy composition, surface finish, and process conditions. Best practice is to test the selected rust preventative on a small, non-visible area first. This confirms that the protective film leaves no haze, spotting, or discoloration under actual storage or operating conditions.
Residue-free alternatives for aluminum and copper protection
For applications where zero surface residue is required, ZERUST® VCI (Vapor Corrosion Inhibitor) packaging solutions provide an effective alternative. ICT® VCI film, ICT® VCI paper, and VCI emitters such as Vapor Capsules, ActivPak®, and Z-PAK® protect aluminum, copper, brass, and steel without direct contact.
VCI technology works at the molecular level and leaves no coating behind. Consequently, this makes it ideal for aluminum or copper parts that must remain clean, bright, and immediately ready for welding, soldering, painting, or assembly.
System-based selection of non-staining rust preventatives for aluminum and copper
Selecting the right non-staining rust preventatives for aluminum and copper is part of the ZERUST® Z-CIS® Corrosion Inhibiting System methodology. This system-based approach ensures the correct product, application method, and protection level are chosen based on alloy type, environment, and storage duration.
For application-specific guidance, ZERUST® technical service experts can help you identify the most effective and appearance-safe corrosion protection solution for your aluminum, copper, or multimetal components.
