My general cleaning is changing the paper and and giving the tubs a wipe down with baby wipes. I don't really have a schedule, just as they dirty their tubs. I actually am due a good cleaning though. I have chlorhexidine I ordered but haven't used it before. But I absolutely hate using diluted bleach because it makes me nervous that I won't get it all rinsed well. With chlorhexidine, my understanding is you just spray and wipe down?
