I'm a materials scientist, and I can tell you that the main plastic components used in plumbing products are generally polyolefins (polypropylene, polyethylene and polybutylene etc...). They are highly chemically inert to caustic solutions so you shouldn't have any problems there. PVC is not quite as resistant but for the short periods of time you are looking at during cleaning with an NaOH solution, there should be no issues. Similarly, silicone sealant used for baths is a cross-linked silicone elastomer and is also inert to caustic solutions. I'd advise that after washing rinse thoroughly with water. Most metals and alloys are fine except Aluminium; which could rapidly corrode. I hope this helps!
