How are y'all cleaning baby bath tubs?

I have a babypatent aqua scale bath that can't be fully submerged in water d/t electronics & batteries for scale & temperature sensor.

The actual bath time is super easy & fast.

Cleaning the tub after the bath is not. It's hard to fit near the kitchen sink to properly drain & it won't fit in the sink to scrub & rinse out after use. My SO wipes it down with a towel & either uses rubbing alcohol or Clorox wipes after. I prefer to try to use dish soap & water rinse cuz I'm worried about chemical residues. Either method takes a while.

What are you guys doing to clean your baby tubs with electronics or too big for ur kitchen sink! after use?
