Hi Laura,
I’ll write in English to make it a little bit easier for you.
With the prefolds. Do you have a front or top loader machine?
You can do a trial first to see if there is any build up in the diapers.
Diaper odor is most likely caused by detergent build up. Run your diapers through an extra hot wash with no soap; if there are any suds, the detergent did not rinse out completely, and this residue is what causes the ammonia smell when the diaper gets wet again. Run your diapers through an extra cold rinse cycle after washing or use less detergent, or switch brands to prevent detergent build up.
Most mamas I know try to strip stinky diapers. Not the most ecological way but that’s what a lot of mamas do – so here we go:
“Stripping” is the process of removing detergent build-up and from your diapers. These residues can cause waterproofing to wick ( with AIOs ), or persistent odor problems, or rashes. It works also to remove germs from the diapers. Begin with clean diapers. Fill washer with very hot water ( if you have a top loader or start a hot cycle with a front loader ) and add a few scoops of oxygen booster ( like oxi action ). Allow it to agitate, and then soak for a few hours ( just stop the machine ). Rinse and then run a hot wash with nothing but water. If there are any suds during the wash, repeat the plain-water wash until there are no suds. That should help. It’s best if you do not return to using the same detergent that caused the problem. In fact, repeated washing in a residue-free detergent will also remove residues, just not as quickly as an intense “stripping”. Some people have found better success with hand-washing in a sink filled with hot water and dish detergent, where you can scrub each individually with a nail brush to speed the removal of residues. That may not be practical, however, if you have two dozen diapers! This is meant as an occasional treatment for your diapers, not as a part of your everyday wash routine.
Other possibilities are already posted by the pp….
