Cleaning LDPE Squeeze Bottles.

[NU_FTW]

So i have been using glass for the past 3 years glass for storage glass droppers for filling tanks, have stayed away from plastic anything.

I got some 100ml LDPE squeeze bottles and i want to ensure they are clean, so what process do you all use when you have brand new bottles come to get any machine oil etc out.

Why not dish soap but rinse better than usual. E liquid does not host micro organisms so e liquid cannot spoil like food.

All I do is wash them with hot tapwater and alittle dishliquid. Rinse them out several times, shake as much water out as possible, and let them air dry.

Its not about anything organic that i worry about, it is about machine oil from production just wondering what method people use my wife will love me if she doesnt have to use glass dropper bottles and hear me gripe about her over-tightening them to where it ruins the rubber seal.

LDPE is all I use for my mixes. Hot water, dish soap & a thorough rinse does the trick...

I just use hot water, and a good shake, rinse/repeat, and then tap the bottle on some towel to get any left over water out, and then air dry.... Dish soap would probably be good to do as well, couldn't hurt. I now use LDPE exclusively with dropper tip for my e juice..Long term storage I use cobalt...

Is it the same process for cleaning them after they've been used?

I've done it.

I've done it.

Thanks I was hoping that was the answer

Though, I try to re-use them with the same flavor profile juice just in case the previous flavor hasn't been completely eliminated.

When my juice bottles still have an odor after washing, I soak them in plain tap water overnight. The bottles need to be completely submerged so I put them in a plastic bowl or tub with a lid and fill it as full as possible. I think the chlorine in the tap water is what does the trick, so if your water supply is not chlorinated this may not work. They are usually odor free after this treatment. Be sure to soak the dropper tips and bottle caps too.

Pretty much, I usually let the used ones soak overnight...

LDPE bottles are blow-molded, and as such no machine oil would come in contact with them undergoing that process. If somehow machine oil inadvertently spilled or otherwise came in contact, they would likely be (or least should be) rejected within the manufacturing facility. If you've ever received new bottles from anywhere that are contaminated, it most probably happened after they left the factory.

I just wash them out with hot tap water and allow them to dry. I do my mixes in 60ml glass bottles and transfer them to LDPE after the steeping period to free them up for the next mixing session.

What you'd be concerned about with new PET and LDPE plastic isn't machine oil, but rather mold release agent. Way back when, it was a nasty petroleum based film that you had to wash off your polystyrene plastic model car parts if you wanted glue and paint to adhere to them. We used dish soap and warm water then, and that's what I use now, though I've never actually seen evidence of release residue on any of my PET/LDPE bottles.

I still wash mostly for "mental clarity", but I really wouldn't be too concerned. Release agents used (if any) have got to be safe for food use and the manufacturing process appears to be exceptionally "hygienic" :

My experience has been that contaminants in bottles will be obvious if they're still there after washing. Water droplets will either never dry completely or take an abnormally long time to evaporate. Try washing a bottle that's had "essential oil" in it and you'll see what I mean.

I understand they are blow molded. But how... Air compressors and lines are notorious for having oil/contaminants in the air lines. Not knowing exactly how they are made with what sort of air system aerosol oil could be making it to the inside so was just curious. Better safe than sorry

Loving all the replies here.

True. Possible for all kinds of contaminants to be introduced during forming. Look at video I posted. That dish soap bottle being stress tested has just come off the line, you can see there's still some water drying in it. They're washed as part of the manufacturing process. But you should definitely wash them as well. I'm more worried about contaminants that are introduced after they leave the factory.

Dish soap and water, air dry. I've never had a foul taste or saw contaminants in plastic bottles yet. A simple wash, just to be sure, never hurts though.
