Isn't safe to clean the Hanna glass/quartz? Cuvette in an ultrasonic cleaner?

I don't see why not. Many labs use heated ultrasonic cleaners with a mild detergent or acid such as HCL or HNO3 for their glassware.

I usually rinse in RODI immediately after each test. Every 5 to 10 tests or so I use Isopropyl Alcohol followed by a soak in DI. Alkaline detergents can etch the glass if left too long, whereas Isopropyl Alcohol is acidic and completely safe. Also, if there's a residue left it separates out from salt water.

Also consider storing your cuvettes full of RODI water, as this pretty much eliminates the need to clean them.

You can use ultrasonic to clean them but with out adding a surfactant to the water you wont get any cavitation. Glass is 100% safe in an ultrasonic bath though. I personally clean mine with distilled vinegar if they get stained from being lazy and rinse them in RODI.
