Hi,
I left cooked rice out (by mistake) for 3 days 
.
I just saw rice turned bright red. It smells a little too. I have thrown the rice in garbage. But I don't know know how to clean the aluminium cooker. I am worried this might be some really dangerous bacteria. I have never seen anything like this before.
I couldn't find anything helpful on internet.
You can see the condition of rice in the link below (mine are pretty similar) but there is not much information.
Please help. I don't want to throw my cooker but I don't think I can use it until I know how make it safe and hygienic again.
Thanks in advance :)
