Firstly let me introduce our product first.
We produce Malted Milk Powder and Coffee.
Especially, we packed the Malted Milk Powder with a lot of packaging: sachets, aluminum bags and Glass Bottles.
Now, I have a problem with Empty Glass Bottles.
I found some white particles that suspect as mold inside the Glass Bottle.
That was 1 to 3 pcs inside the jar. Sometimes, it was outside the bottle.
We discussed how to solve the problems and we got 3 ways to kill the mold.
1. Spray with alcohol inside the bottles.
2. Pass through the heating tunnel.
3. Pass through the UV Tunnel.
The one I want to know is all these ways can exactly kill the mold?
If we will wash the bottles with hot water and after drying, is it secure for growing mold?
Thanks you all so much.
