Default Which Stain Removers work best? URGENT

Hi, I am doing a science assignment on "Compare the Effectiveness of Stain Removers". How will I measure the amount of stain left after I use the Stain Remover? I do not have a colorimeter and will not be able to get one.

Any help appreciated, thankyou.

Well, there are two things to a stain.

Color, and surface area. You can estimate the surface area of the stain.

As for the lightness/darkness of the stain, depending on the color of the stain, you can try to find/make a chart. For example, from a scale of 1 to 10, black/dark brown being 10, and light yellow being 1. This is the best way I can think of to keep your rating constant.

Then you'll have to combine these two together to form one score so you can compare the stain removers. For example, a surface area of X could be 1 and a surface area of Y could be 10. Add the surface area and the color score together to find a score to compare.

You'd probably don't want to be blunt as much as I am about this. I just got another idea. If you express the stain color as a fraction, and then all you have to do is multiply it by the surface area. It's more accurate that way, but I suppose that is too much work.

If you need anything but can't find me (I'm often gone for long periods of time), just PM me. I'll get noticed right away!
