Chlorine Dioxide Holding Solution (CDH)
Chlorine Dioxide Holding Solution (CDH) is made by activating Sodium Chlorite with either citric acid or 4% to 5% hydrochloric acid (HCl) over a longer period. It differs from CDS in that CDS contains only the gassed-off chlorine dioxide gas in distilled water, whereas CDH is produced by activating the MMS in the distilled water.
The benefits of CDH over MMS are that the horrible taste and smell is virtually gone and larger amounts can be used to target problems - akin to CDS whilst retaining the full properties and potential of MMS.
Hydrochloric acid is available in various concentrations and purities generally in the range of 25 or 30% plus. AR grade is best but the important thing is to dilute it down to 4% to 5% in distilled water.
To dilute 32% HCl down to the required range of 4 to 5%, use 3.5ml of HCl and add it to 21.5ml of distilled water which equals approximately 4.66% and you have 25ml of this - perfect for the method below.
To make 3,000ppm CDH,
For making different amounts:
1 litre of water + 50ml of sodium chlorite and 50ml of 4 to 5% hydrochloric acid.
250 ml of water + 12.5ml sodium chlorite and 12.5ml of 4 to 5% hydrochloric acid.
330ml of water + 15ml of sodium chlorite and 15ml of 4 to 5% hydrochloric acid.
This solution should be kept in a cool dark place with the lid on to prevent off-gassing and will last quite awhile.
One ml of this solution is the equivalent of a 3 drop dose of MMS so refer to the protocols page and substitute the amounts accordingly. For example, when starting protocol 1000, instead of activation 8 drops of MMS and adding to 1 litre of water, you woul add 8ml of CDH instead. This would build up to 24 ml in a litre of water instead of the 24 activated drops of MMS.

To make 3,000ppm CDH,
- use a glass bottle or jar & fill with 500ml of distilled water
- add 25ml sodium chlorite 22.4% (28% of 80%)
- add 25ml 4 to 5% hydrochloric acid as above OR 25ml of 50% citric acid (note: if using citric acid the smell will be different)
- place lid or cap on the container, mix up gently and allow to stand 12 hours at room temperature
- refrigerate for 3 hours before use
