I bought MB in 2.303% concentration. If I divide 2.303 by .1 =23.03

So, does that mean if I add 23 drops to 1 drop of the 23.3% that I get .1%?

I know someone said to put it in a gallon of water. How much 1 drop? Isn't that 200%?

As you can tell, I am not understanding this AT ALL!

Please help! Thank you!

All the formulas for breaking down Methylene Blue 2.3% caused nightmares of high school math & science, resulting in an Excedrin PM headache lol. I took the info everyone provided and it averaged to be 1 part 2.3% MB : 22 - 23 parts distilled water.

Still afraid to try it, I called a friend of a friend who's a chemist - he said 1 part MB to 23 parts water. (The K--don is 2.3% water solution, zinc free.) I hope this helps!
