Thanks for looking at the Ecover Zero Non bio. It's very reassuring to have your thumbs up.
Now for the acid stage, I see that - in the absence of Citranox - you suggest supermarket distilled vinegar diluted 50/50 or 75/25 with distilled water, with an additional few drops of wetting agent. Is the Dehypon ok to use as wetting agent in this mix?
As an alternative to vinegar, is worth considering a solution made up from pure citric acid crystals which are easily obtained here?
Thank you,
Rob
