My gandmother and mom, still uses a bar soap that is called fels-naptha. Made by the Dial company....it is great for stains....you get the garment wet, then work the soap into the stains....great whitener also....on delicates, I get the garment wet, then just work the soap onto my wet hands (small amount) then work the area in my hands...that way you only get a small amount, but can add more, and you are not directly applying it to the cloth.....it is a bar soap...their 1-800-258-3425 or their website...
www.purex.com...my grandmother says the ingredients have not changed since she started using it...many many years ago...with a wash board....(which I have now as an antique). Good luck
