Medline Mini Urine Analyzer 120

Hello, in our hospital we are using Clinitek UA analyzers, but recently, I had to learn Mini Urine Analyzer 120 as a technical consultant , and I am a little bit confused with the maintenance section for this analyzer (from the manual), the manufacturer prompts us to use 0.1 N NaOH for cleaning, as well as sterilization step. If you are using this analyzer would you mind sharing with your current practice how do you clean the instrument. Also, if you would wish to share with the maintenance/cleaning procedure that would help a lot. Thank you
