Answers:
sorry to hear about the stains.i would first trt OXI CLEAN,
but maybe you already have.
I did find the following link to a distributor for sodium dithionate
http://www.ecochem.dk/prod_uk_i-z.htm...

but after all my research...it almost appears that this chemical is not available to the lay person...you may want to ask your dr. or pharmasist.
this link (company) looks like they are located in europe...but it says they will ship anywhere worldwide

Please make sure you print out the MSDS sheet for this chemical before using.

Good Luck and best wishes
