In either case, the inner liner is made using different material properties than the structural portion (Hence the name dual (meaning two) and laminate (a word commonly used for a layer of a composite material))
To clean especially dirty tubs, let the cleaner sit on the surface for up to twenty minutes. This allows the cleaner to break down the dirt and oils to be more easily removed.
