Bioscientist is helpful, nice and has lots of friends here

you can simply take nine pieces of white cloth. Put one stain on each cloth (you have 3 different stains). Do this three times, as you have 2 stain removers to try out, and the third set will be the control without any stain remover. After applying the stain removers (or no stain remover for the control), you can compare whether the stain remover has effectively removed the stain.
