How to sterilize rubber stoppers.

[Liquidex]

Alright so many bros asked me how to sterilize rubber stopper for home brewed juices.

Since its rubber you cant just dump them into the hot oven as they will just melt down so heat treatment is not really an option.


Heres what you can do.

Goto grocery store, and pick up these two.

1. 3% hydroperoxide solution.

2. 70% isopropyl alcohol.

Now, we are going to use hydrogen peroxide as cleaning agent. You can technically use it as anti bacterial as it DOES kill bacteria, but it takes around 12 hours to completely kill broad spectrum bacterias. And who got times these days anyway lol

Do wash rubber stopper, do the following method.


1. Dump all the rubber stoppers into the tupperware like this

2. And pour in good amount of hydrogen peroxide.


3. Put the lid and make sure its closed tightly, and shake the tupperware like a mad man. Shake for good minute or so.


4. Now, prepare for alcohol in a tupper ware. We are gonna shake like mad man again but this time in alcohol solution.

5. After shaking in alcohol for good minute or so, now prepare alcohol washed sterilie tupper ware.

6. Just put them in to the tupper ware and dry it overnight. You can open the lid little bit but you have to put it in the place where there is no air movement otherwise it will be conteminated again.

7. After drying , just use the rubber stopper.


Done

You can dip in BA right before putting on vials too.

This. They can be baked at around 250-300 as well then dipped into BA before using them.

i soak mine in 5% bleach solution for 30 mins, then in 70% IPA for 30, then put into foil that has been wiped with IPA and dry them at 250 F in the oven for an hour or two, no melting at that temp and soaking in bleach sterilized them, so the main purpose of heat was just to dry them, works out pretty well
