So I want to have my little guy swim around in the tub in my apartment, the sink in my kitchen is just too shallow and he constantly tries to jump out. I scrubbed out my tub and cleaned it better than what it was when I moved in and rinsed that sucker as well as I could with hot water. However, I'm worried about possible residue still being left over and I'm not sure if my cleaner is beardie safe. What do you guys use that's effective yet safe? Or am I going about this the wrong way and should I just get a plastic storage tub for him to swim around in?
