Can I use an acidic cleaner and an alkaline cleaner one after the other?

Yes, in some professional two-step processes, but only with care. Each product should be applied and rinsed off thoroughly before the other is used, never mixed or layered on the surface. Two-step washes can remove both inorganic and organic contamination effectively, but they are also harsher on protection and sensitive surfaces. Follow the manufacturers' directions and keep both products off hot panels.
