A woman who soaked six of her bras in a simple solution of two cleaning products was shocked to find the water turned a disgusting shade of dark brown.
The Daily Mail shared this story of a woman who soaked the bras for 30 minutes in a solution of Cold Power washing detergent, Sard Stain remover, and cold water. Both brands are sold in Australia, where the woman is from.

It shouldn't be done regularly, as some fabrics can get worn out from this process.
