I always just use the following:
1.Fill the bath to the level and temperature suitable to you. (not to hot)
2.Take a clean glass, add 20cc/ml CDS 3000, 10cc/ml of DMSO wait 2 minutes to bond.
3.add the solution to the bath water
4. Swoosh the water around with you hand.
5. immerse your body for 20 minutes, if water goes cold top it up with hot but not too hot.
6. do not put your head in the water, just up-to your neck, lay and relax with some of your favourite music for 20 minutes.
7. Always ensure the bath is clean and never add bubbles, soap etc this is just to soak in. DMSO drives the CDS into the blood and bones, and will carry any soap etc with it.
