Edelbrock intake manifolds are manufactured from a sand cast process utilizing 808 aluminum alloy and have an as-cast wheel-a-brated finish. As-cast is defined as a raw aluminum finish without any protective coating. As-cast aluminum is porous and can absorb under-hood chemicals such as dirt, grease and fuel, resulting in discoloration, rust, or staining. All Edelbrock intake manifolds are as-cast unless offered in high-luster EnduraShine or PermaStar® coated finishes.
Once a porous aluminum finish is stained, it can be very difficult to find an environmentally safe cleaner that will actually extract the blemish from the pores of the aluminum. In its research in finding a safe and effective alternative, Edelbrock has found an aluminum cleaner option that can work effectively: OxiSolv Aluminum Cleaner. It is important to follow OxiSolv’s instructions to prevent damage to other parts on your engine.
Manufactured by Daubert Cromwell, a manufacturer of industrial and commercial cleaning products, Evapo-Rust is effective for use in cleaning as-cast aluminum intake manifolds, cylinder heads, and water-pumps when used as directed. Edelbrock does not sell Evapo-Rust, however you can call for assistance at 800-535-3535 or send an email to [email protected].
