How to clean slimy drink bottles

by Katrina - The Organised Housewife

Some drink bottles come with very small opening making it hard to get a sponge or a brush in there for a good clean.  Over time if a drink bottle is not cleaned properly or left for a period of time in the car or bag it can become quite slimy.

A simple trick to clean slimy drink bottles is fill it up with water and drop in a denture tablet, these can be found in the toothpaste section at the supermarket.  Let the bottle soak for a few hours and give it a good rinse and clean with warm soapy water.

That’s guck is so annoying and it keeps reappearing! I’ve invested in a big pack of pipe cleaners. Just bend the tip into a U shape. They’re really good for getting into the straws as well.

To get rid of mould on lids I soak them in Milton(used to sterilize baby bottles). You could soak the whole bottle.

I soak my dish cloths in the Milton solution, {1 Tablet to 2 Litres of water) and its also great to remove stains from inside of coffee cups.

Would you be able to soak them in bleach then rinse in running water to clean

I wouldn’t Louise, I would keep bleach well away from surfaces and products that are used for eating or drinking.

That build up is a biofilm, like plaque on false teeth. Best way to disrupt a biofilm is to scrub it off with hot soapy water and some kind of brush. A toothbrush gets in most places. You can bend the handles if you heat the plastic to make it easier to get inside rims. Then run em through the dishwasher.

I clean plastice bottles with hot soapy water, about a tablespoon of rice, and a whole lot of shaking. It helps to get the gunk on the bottom of the bottle that is hard to reach with brushes.

I clean my water bottles with a bottle brush (from the baby aisle).

Monica, i have also used the baby bottle brushes too, they work well i agree . I like to also use the denture tablets for those hard tricky places i can’t get to with a brush.

Katrina, do you know if the denture tablets can be used in steel drink bottles or just plastic? (I recently replaced all of the plastic drink bottles with steel!!!)

Use the denture tablets in the toilet to clean. Works a treat and is sparkling white. 1in the system and 2 in the bowl.

That’s a great idea with the denture tablets!
I recently cleaned out bottles, I didn’t know what with, so I crushed egg shells, and dropped some dishwashing liquid and white vinegar, shook like crazy and left it over night. Slime was gone, and I used the same liquid and cleaned rims with a soft scourer.
