Coppers PET in hot water?


#20

Recommended Posts

Hi guys,

 

I have somewhere read that you should not expose the PET bottles to hot water.

 

I always try to rinse the bottles in water just after I have poured them. But I only use cold tap water in fear of damaging the bottles. The problem is, it just doesn't feel as clean using cold water opposed to hot water. They are spot on clean when looking at them. But I always feel there is a smell of old beer left. Especially if I put on the cap and open them a few days later.

 

When I have rinsed glass bottles, I just use hot tap water (as hot as it is) and there is never any beer smell.

 

It would be very very convenient to use hot as hell tap water to rinse the PET bottles after use. But can I do that?

I have never been there but I believe hell is really, really hot. I should be able to tell you at some stage in the future [devil]

 

Anyway it depends on how hot your tap water is. We have a temperature controller for our hot water system and the temperature doesn't exceed 50 degrees. It seems to be ok for rinsing PETs.

Hot water is fine if used with a bit of common sense. You put a bit of hot water and give it a shake, tip it out and finish with cool water to cool the plastic, Practice with a soft drink bottle if you want to see what hot water can do to plastic bottles.

 

When it comes down to it though the most important thing is to rinse your bottles with hot or cold water asap after emptying them.

Had to check it out, and my tap water is 62/63 C. "Hot as hell" might just have been a little bit exaggerated [innocent] .

 

But what is potentially the worst thing that could happen? The bottles deforming? That is no big crisis. You see it if it happens and you replace the bottle(s). And as you say Muddy, cool the plastic down again.

 

Initially I was more worried that the hot water could somehow react with the PET thingy stuff and release harmful chemicals that could be a health issue and what not.

 

I guess I am seeing monsters under the bed here [w00t] , and all that is there are dust bunnies [cool].

I believe I used very hot water on some brewcellar PET bottles and coopers PET bottles some time ago. Some of the brewcellar ones kind of deformed a little bit, but seem to be still ok to use. The coopers ones appear to be a little thicker and didn't deform at all.

Now's as good a time as any to mention it; some of the bottles you gave me were rooted, don't know if it was sitting in the boot of your car, or something else, but I ended up throwing about half a dozen of them out, some even had holes in them.

 

It's all good, I just wanted to mention it and purge.

I still have more bottles than I need, and am grateful for the 50 odd bottles I wouldn't have if you hadn't given them to me.

I feel better now.

 

So I guess add to the hot water thing; don't keep your bottles in a car boot or in sunlight, or anywhere that they may get a bit warm. Generally room temp is fine, unless your room is a furnace.

They were Weggls bottles so not sure what he did with them - He kept them under his house in the cool. I don't think a couple of hours in the car boot would have much affect on them.

 

You can have some of my own bottles if you want - They have never failed me [cool] ....even when exposed to a few seconds of hot water [innocent]

Don't use them. made about 500 bottles whithin 1 -1/2 years they were all flat. seems the PET leaks gas out through the bottle walls. Coopers should put a warning on the box about this FACT.

Made 500 bottles the bugger all went flat

so i'm on this forum just to have a chat

the best bet is to stick with bottles made of glass

as for PET you can shove them up you jumper

He Muddy, I rescued the bottles bought 3, 5L PET kegs and gassed them as require. The beer had aged some 5 years some of the best beer I have ever tasted.

some bottles i re-gased with sugar pills they came up ok, but will not leave then more than about 6 month in case the buggers go flat again.

G'day All

 

There have been other threads on this topic before.

 

But the basic advice is "Don't wash them in hot water". Main reason is not about chemicals leaching out, but simply that the hot water can distort the bottles. And that is a very good reason why you might get flat bottles - the gas leaks out.

 

I've been using PET's for a long time and never had a flat bottle that I couldn't explain as another cause. Had a few volcanoes, but again, other reasons for that.

 

Some blokes have been guilty of screwing the caps on too hard. This can distort the plastic type seal in the cap. After a while, the integrity of the seal can fail. I just screw them on hand tight. Yeah I know some blokes have hands like vices, me included, but you really can tell when the cap is on okay. Never use anything to twist them tighter.

 

Just my thoughts, but works for me.

 

Cheers

Bill

Have been using pet bottles now for 10yrs. Only changed from glass as worried about kids getting near them by chance and knock one over and we know what happens to some others.

Every now and then I get one that the lid didnt seal. But other wise still using bottles from when I started.

 

Found the caps with the white plastic lining in lid work best. Just changed all my lids and the newer ones with like a star pattern seem to fail a little more.

[bEER -O CLOCK,

You might have success if you turn them over rather rapidly, I had no problem with ones i drank within a year. But ones that got past 1 1/2 years went flat.

So if you want to age them go glass.
