Castrol Kleen® 3652
Mild Aluminum Cleaner
Castrol Kleen 3652 is a mild alkaline cleaner primarily used for cleaning aluminum. Kleen 3652
performs well in soak tanks. It is particularly effective in agitated soak systems for in-process cleaning
of copper, brass and aluminum, as well as steel and cast iron. At the proper concentration, Kleen 3652
can be used on ferrous metals. However, it is not designed to provide ferrous corrosion protection.
• Ambient temperature operation saves energy and energy dollars.
• Effectively removes a variety of soils enabling users to consolidate the number of cleaners used in
Low spotting in applications where alkaline salt residues are unacceptable.
