Here's how I decaff my beloved Colombian coffee:
In a 250 ml wash bottle, I put 30 drops of the sodium chlorite solution and 30 drops of the citric acid solution, let it develop for a minute then fill with distilled water, put the wash bottle squirty lid - WITHOUT THE DIP TUBE - on it and stick it in the fridge.
For my coffee, I squirt it directly into the prepared coffee for a slow 3 count. Voilà!
Back when I was drinking my coffee straight, I used it to decaffeinate myself with a long squirt in a shot of water. Then tried it on my coffee and it didn't change the taste at all. I doubt my coffee is totally decaffeinated with a slow 3 count squirt as there is zero aroma of MMS, directly after, but it's definitely a lot LESS caffeinated.
If you use the dip tube, it will oxidize in pretty short order so I remove it. I have to turn it upside down to dispense it, which takes a teeny bit of practice to do it without making a mess, but the bottles, themselves, are non-reactive material whereas the dip tubes are not.
