Best laundry detergent to remove urine smells?

[desklamp]

Boring thread alert.

My DD has a medical condition and as a result struggles with accidents throughout the day. I have been washing her clothes at 90C but they are still smelling a bit whiffy after a thorough pre-wash and wash. She puts her clothes in a small bucket and I wash them every day or every other day, depending.

Can someone please recommend a better washing routine, or stronger laundry detergent than the bog standard stuff I'm using?

Should I rinse with vinegar or something like that?

Surf powder, plus some Zoflora in the fabric conditioner drawer instead of fabric conditioner.

Line drying i found was most effective way of getting rid of smells

Bio powder is probably best. Maybe use dettol laundry cleanser or zoflora in the fabric softener compartment

Dettol laundry cleanser

There is a urine smell remover spray you can get on amazon. Sorry I don't have a link - I think it's for furniture and needs to soak in but it might be worth a try?

Urine remover sprays use enzymes. Bio powder also contains enzymes so can work too

My current tried and tested methods due to potty training accidents here are...

White vinegar- Mix 1 cup to 3 cups of water and soak the clothes in it for a few minutes.

Bicarbonate of soda- add 1/2 a cup to the wash.

I’ve found that if they sit too long with the urine on them the smell becomes even more horrendous to try and get rid of.
I also second the other opinions on here that a biological washing powder is more efficient and then line drying the clothes outside.
