How bad is the stain? I remember using it when I was young but I don't recall having a really bad stain. Maybe I was too young to notice my appearance...

skinurghs, thanks for your tips. I have not been drinking lots of water lately and have been lacking sleep. It has definitely helped aggravate my Eczema, but I believe the massive outbreak I am having now is due to a trigger. I am currently trying to pinpoint the trigger, but your tips have definitely helped reminding me what I should be doing.
May I ask what do you mean by using table salt to wash? Do you mean washing the affected Eczema areas with water diluted with table salt? If so, how many teaspoons do you use? Advisable doing after your shower?
As for the original question, my mother recommends I find a big enough tub for me to soak myself in. Unfortunately, I am not 5 years old anymore so I need to find for a huge tub. I'm not willing to stain the big 'proper' tubs I have, so I guess that method is out of the question :S.
