No sterilising question - How hot is 'hot soapy water'?

24 replies

hjscho · 29/06/2007 14:24

This may seem like a silly one...
I am fed up of sterilising and have read a few threads about not needing to do it. I just wondered how hot the water should be when people say hot, soapy water. Is hand hot good enough, or should I be wearing rubber gloves and getting the water even hotter?

As hot as possible I would imagine, have you a dushwahser cos that does the trick as well

mslucy · 29/06/2007 14:33

how old is the baby?

I'm afraid I'm a slob and gave up on sterilising when he was about 9/10 months.

By that age they're literally rolling around in muck so what's the point of getting all worried about germs on a bottle?

QueenofBleach · 29/06/2007 14:34

We gave up at 6 months

hjscho · 29/06/2007 14:40

3 months old, but I cannot see the point of sterilising when DS puts a dirty tea towel in DD's mouth this morning whilst attempting to clean away her sick. Surely there are more germs on the tea towel than on a well cleaned breast pump and bottles?

When ds was very small (under 4 months roughly) I used very, very hot soapy water and gloves. When he got a bit older I used hand hot soapy water. The key issue seems to be ensuring there is absolutely no old milk lurking in some crevice in the bottle or teat.

When dh washes a bottle he uses luke warm scummy water the consistency of vegetable soup, sticks it on the side and then I wash it again.

hjscho · 29/06/2007 14:48

Bookthief, how often do you renew your bottle brushes then? Surely they have an impact on how clean the bottles are.

Hot enough to need rubber gloves, ideally. Or put them in the dishwasher. I never sterilised for dd2, and only half-heartedly for he others.

bookthief · 29/06/2007 14:52

I don't wash many bottles as still bf so am still using the same bottle brush & it's pretty perky looking. You're right, you should probably change it fairly frequently if you're using it daily.

Brangelina · 29/06/2007 14:53

Just hot enough not to feel it with rubber gloves I suppose. I never sterilised, just washed and rinsed. Make sure you rinse well and get rid of all the washing up liquid though. Nothing worse than that soapy taste and cocktail of chemicals....

mumto3girls · 29/06/2007 14:55

Surely sterilising for a baby of 3 months is par for the course...? Not too taxing in the big scheme of things..

By the way, stand your bottle brush in a very mild bleach solution over night (milton would be fine) to radicate all germs.

muppetgirl · 29/06/2007 15:00

We thought sterilising was silly when he was grabbing things and stuffing them in his mouth all the time, 3 months still a little young though...?

We then switched too sterilising tablets and had a bowl of water always on the go, put dummies, washed bottles in there and rinsed when needed.

Don't have to worry about exact temperature then.

Brangelina · 29/06/2007 15:05

Where I live the maternity and paediatric hospitals themselves tell you not to bother sterilising as there is absolutely no need, even with newborns. I mainly bfed but the odd time I've had to use a bottle (inc once in hospital at 6 weeks) I never sterilised or even just boiled. In the H they told me just to rinse the teat under a hot tap but I insisted on using a little soap at least.

muppetgirl · 29/06/2007 15:10

....really?

I'm amazed!

RTKangaMummy's original (legendary ) thread on this is here

This is the email that she sent/received from the microbiologist at UCH re: sterilising :-

**

"THIS IS A COPY OF THE EMAIL I SENT TO UCH THE MICROBIOLOGY CONSULTANT {I have deleted my RL name and the microbiology consultant's name also my DS name and dob and DS consultant's name at UCH}

Hello

Our twins were born in 1995, and twin 1 died but twin 2 survived and was in NNU for 3 months. He is now 10 years old.

We were told when he came home that we did NOT need to sterilize the bottles or dummies.

We were told that the microbiology dept advised that the correct way to clean everything was to wash EVERYTHING in very HOT soapy water and put on kitchen roll to AIR DRY.

I was wondering if this was still the advice that was given to parents when they leave the NNU.

Thank you for your time

This is the reply that I received this afternoon. So this is the advice given as of September 2005.

Thank you for your email. Yes you are right about the bottles. However I cannot emphasize enough the importance of cleaning the bottles so that there is no dried or caked milk at the bottom of the bottle as this will encourage bacterial growth. Clean and dry are the operative words. Bacteria thrive in warm moist environments. In addition the greatest attention needs to be paid to hand hygiene before preparing feeds. A bottle steriliser is not a substitute for proper hand hygiene and may even give a false sense of security. For those lucky enough to have a dishwasher, the hot cycle in the washer after removing milk debris mechanically is good and sufficient cleaning method for bottles, provided they are then stored clean and dry.

This advice obviously applies to this country only as we are confident that there is no faecal contamination of piped/ mains water supply. I cannot comment on the state of the water supply out of the UK.

do you know someone on my antenatal group asked about dishwashers and the hv made the poor woman feel very stupid!!!

Thank you so much for that and I will copy it into a word doc to sho my dh and hv when they complain i just use the dishwasher.

Btw, all my three were in the same neonatal unit as RTKM's (not all at the same time!) and we received the same information.

I figured that if this was the regime they were recommending for vulnerable preemies, then it was good enough for my 9lb porkers.

frogs · 29/06/2007 17:02

I also know several GPs as friends and family, and all have dishwashered bottles instead of sterilising.

hjscho · 29/06/2007 20:10

I knew about the dishwasher and I have read RTKM's thread, but I only need to do a cycle every couple of days. I am bfing and was just wondering if a good hot (but how hot?) wash would suffice for my breast pump and 1 bottle with teat.

ELR · 29/06/2007 20:12

didnt bother to sterilize with ds but breastfed till 6months at 3 months had expressed and just used hand hot water and rinsed well left to dry on kitchen roll

ELR · 29/06/2007 20:13

same with breast pump

Lyndag · 29/06/2007 20:31

I was advised that the dishwashers in the US go on a hotter cycle and are suitable for using to bottle washing......however UK dishwashers don't get as how

bookthief · 29/06/2007 21:49

The other thing is that breast milk does not grow bacteria as quickly as formula. If you use your breast pump more than once a day you can actually just stick it in a plastic bag in the fridge between sessions and it'll be absolutely fine.

I don't have a dishwasher but issue is about washing off the bacteria rather than killing them with heat so the temperature of the water isn't really relevant past a certain point imo.

bookthief · 29/06/2007 21:50

(ie that milk is fatty so will need water to be hot & soapy in order for it to be cleaned off thoroughly)
