This soap (in its raw slab format) is a Mild Green Household Soap recommended for laundry and household use (e.g. collars, cuffs, floors, doorsteps, surfaces, stain removal, etc). Since all Fairy Green Soaps were discontinued several years ago this soap has become more and more popular over the years.
These bars really are the 'big boys of soap', ready to do all the heavyweight jobs around the house. Cut them with a cheese wire or a hot knife. You can grate the bars to make a washing solution too.
