I got some moldy christmas decorations (saaad) and I'm trying to salvage what I can, so I put the textile stuff (the ones that appeared ok) inside the washing machine.

What temp should I use?

I found something like a report or something that states that the enzymes should work at max 60°C: https://support.nanotempertech.com/hc/en-us/articles/20923823244177-Stability-of-Enzymes-in-Liquid-Laundry-Detergent-protocol

I also found a reddit post that says that they should work at around 40-60°C(?): https://web.archive.org/web/20251216082333/https://old.reddit.com/r/germany/comments/16q8pp2/on_what_degree_do_you_wash_clothes_in_germany/

My detergent says it's been lab tested to remove heavy stains at 40°C: https://lafamilleatable.com/en/products/p-lessive-capsule-ultimate-active-clean-3en1-skip-8710847917493 (I found a french site with info in english)

From what I gather:

  • 30°C is the minimum operating temp that the detergent should be effective
  • 90°C is off-limits, will probably kill the enzymes
  • 40°C is the lab tested temp, probably optimal temp in terms of power usage-cleaning effectiveness
  • 60°C is the max operating temp, but I dont know if it cleans better or worse than the 40°C option

PS. I picked the 60°C for now.

Yeah youre right on that and some of them got dismembered after the wash cycle finished:/

But I'm dealing with mold and dunno if I had any other option, ughh.. what a mess. Even 60°C may not be enough to kill the mold:/

    You might want to use anti-mold sprays, or something like them which you can soak the decorations in, and avoid subjecting the decorations to a machine wash at all.

    If they're disintegrating, then hand washing is almost certainly the way to go if you're serious about trying to save them.

    There may also be something to be gained by putting them somewhere with good airflow and direct sun, unless the sun will damage them as well. Mold generally dies off if exposed to much fresh air and sunlight
