I have done further research on plastic bottles and the recycling symbols. Here is a brief synopsis:

Recycling number Comments

—————————

1 Used in pop/water/juice bottles. Good for one use but not recommended beyond that.

2 Unsure

3 Unsure

4 Unsure

5 Safe for use and reuse (as far as we know)

6 Not Safe (can leak chemicals)

7 Not Safe (contains BPA)

That’s what I know right now. I’ll try to update as I know more.
