Steam cleaner smelling

Hi All

Can anyone tell me why the steam from my steam cleaner smell of
urine?

I only put tap water and have used a scale remover last month.

I have asked around and got the usual answers of “What have you been
using to fill it up?” lol

Anyone?

Stop Peeing in your Steamer!! LOL

Open all the valves and give it a good flushing out. Make sure you
use a Steam cleaner additive.
