Blue toilet chemicals

Will a bottle of liquid blue toilet chemicals freeze if left in the camper over the winter? A friend of mine says that she left a small bottle of blue toilet chemicals on her bathroom sink in her trailer. She is afraid that the chemicals will freeze and the bottle will burst. She is in Florida and her camper is in Indiana.

I would not worry about it depending on the brand.

Here is the MSDS for Aqua-Kem.

As you can see there is two ingredients in it. Methanol and formaldehyde. Methanol won't freeze.

I keep it in my trailer year around with no problems and it can get down to 15 here.
