I do this every six weeks or so, Geila. I scrub the tub down every ten days or so - depending on how busy I am - working banquets means I don't have set days off so sometimes this gets done sooner and sometimes later. And the bleach water every six weeks or so and I've got one nice, clean and happy tub. I do agree with you that bleach is really strong, though, and I air out the bathroom before using it after I drain the bleach water. The bleach smell lingers but after a few hours is not as strong.
