When I bought my house I was told by previous owner to use Ecover washing powder and fabric softener in the washing machine. Since using this product my whites have turned grey and the cling is well into my petticoats!!! Can anyone suggest alternatives? I have always used Fairy or Daz in the past and Lenor or Comfort.....can these products do any damage? We intend to use Eparcyl (a French product that you can buy on Ebay) and have the tank emptied annually.
