Ironing knickers to reduce UTI

117 replies

My mum told me to always iron the crutch of my knickers to kill bacteria. Just wondering if others do and whether it really does prevent infections. I've never had a UTI but this could just be coincidence.

Just when I thought Id encountered all the batshit crazy ideas.........
I dont own an iron.
I dont own a tumble dryer.
I airdry all our laundry (assisted by a dehumidifier)
M&S knickers (possibly cotton? Ive no idea tbh)
I wash everything at 30c
I must be overwhelmed by illness and UTIs according to this thread. Except Im not. Because obviously.

@Ceramiq sorry but beg to differ. It’s also odd how you ‘know’ the exact temperatures the households you visit wash their clothes on! I mean it could just be they smell sour because they have a very infrequent washing routine altogether. You couldn’t possibly know unless you either lived there or had some very strange in depth conversations. Personally, I go to bed with lovely fresh smelling bedding and clothes and I think I would know that since it’s my life 🙄.

As to people referencing how dishwashers use 50 degrees plus to prevent food poisoning is just such utter nonsense and screams of hysteria! I mean if that’s true, wouldn’t people without dishwashers like me be permanently keeled over and off work because they washed up last nights curry off the plate with tepid water and a smidge if fairy liquid? And how on earth did our grandparents in the pre dishwasher age survive?!

Re NHS, in hospitals of course they’re going to adhere to much higher washing temperatures for the very reason it’s a hospital! It’s riddled with bacteria due to servicing ill people 24/7! Let’s use common sense, if you’re single with very low traffic of visitors and childfree, do yourself and the environment a favour and stick to low faster washes and if you have kids, pets, recovering from illness or elderly perhaps a higher temp would be advisable. It’s not rocket science!

Bodily fluids, and cat hair I prefer 60 just cat and I

Doesn't the washing detergent kill germs? If not, why have we been washing our hands with soap all these years....

😂what a load of rubbish. The only thing that would actually fully kill bacteria would be to autoclav or sterilise, it will do very little the difference between washing at 30, 40 or 60oc

Edited

NHS advice is that 60 degrees for ten minutes kills almost all micro-organisms.

It won’t make it sterile but these things are a spectrum.

Thanks for all the comments. I'll continue to iron my knickers which only takes a few minutes and is weirdly satisfying as they feel really clean.

ECO setting on dishwashers are usually set at 56 degrees or 60 degrees for the same reason. Water at that temperature kills almost all bacteria, thus preventing food poisoning.

And yet those of us who have always washed our dishes by hand - and don't have a clue what the water temperature is - somehow manage to escape food poisoning. Confused

Honestly, some of you are just weird.

Ironing, especially the seams, was a traditional defence against lice and bed bugs. It won’t eradicate an infestation but probably helped prevent one starting.

It's not hot enough to scald, if you wash-up by hand, whereas a dishwasher probably is.

MrsSkylerWhite · 13/06/2025 23:39

Sorry, what?

Really?

Well, that's the point I was trying to make! We don't use very hot water, and yet we remain healthy, so the poster's original claim was a load of nonsense - like much of the "advice" on this thread.

My flatmate used to iron her knickers at Uni. I’ve just remembered! I think probably it did originate as a way to kill lice .

EBearhug · 14/06/2025 09:12

I remember ironing knickers at uni to get them dry enough to wear to go out...

Oldglasses · 14/06/2025 17:29

Life is too short to iron your undies! Modern washing liquids work well at lower temps so there is no need to wash at 60c. I've never had any issue from my gusset!!
Maybe 25+ years ago if you washed at 30c there would be an issue, so a hot iron could help if there was any chance of bacteria going your vag/urethra, but now, no!

Calliopespa · 15/06/2025 00:19

Make sure you let them cool before wearing op! 😬

I’m a minger and am remarkably healthy. I like to think I’ve built up resistance. 🤣

Same. I don't even wee after shagging unless I needed one anyway. Never had a uti. Or thrush or any other bother with my vag.

did anyone actuality ever get ill from bacteria from their own body?

Well how do you think they happen? Anyway on your underwear isn’t from your body anymore than faecal matter is really: it was from your body but was got rid of.

OP I think it’s generally not drinking so the germs in the bladder aren’t being flushed out and the ph changes or something, or especially as people age the tissues become more permeable and ( foul thought) I think there can be transfer of the greblies from the bowel. But either way, I think it tends to have its genesis inside the body.

It's important to wash underwear at 60° in order to kill bacteria.

Yes, I always do that but I've heard that some washing machines don't even get the temperature up to 60° and if they do it isn't for long enough to kill all bacteria.

I think if you are getting recurrent UTIs then there's no harm in doing that as you never know if it might help.
