CDS for external use, what strength?

What is the correct dilution of 3000ppm CDS for external use?
Thanks.

No dilution. At least that is how I use it. And depending on what you are treating, the stronger the better. I have used 12,000 ppm directly on skin problems.

Now, I am referring to the original CDS, not CDS that has added MMS. I would not use that for external purposes.

I recently was able to get rid of a pre-cancer on my head using strong, undiluted CDS followed by DMSO 50% diluted.

Thank you. I searched all over but couldn't find it anywhere.
