The simplest possible remedies to get rid of ammonia are vitamin c ascorbic acid, lemon juice, and apple cider vinegar. I used vitamin c ascorbic acid. Of course this is the ones I prefer for infants. The theory is simple any acid neutralize ammonia, but hydrochloric acid in betaine HCl or just HCl does it faster, but ascorbic acid is more milder and better tolerated.
