Moth Balls Melt Solo Cup

Question

We’ve been putting loose moth balls in solo cups and leaving them around the camper when we winterize. Never had any kind of issues in the spring once we dewinterized.

This last winter was different. The moth balls actually made the bottom of the solo cups disintegrate. It’s as if they melted.

Any idea why? I just don’t want the same thing to happen this winter so Im trying to research it before buying anything this time around.

Moth balls contain naphthalene. And naphthalene is a solvent. Some solvents don’t play well with plastics.

I like you have never had that happen. I have been using the solo cups for years, I would use scissors to make them shorter then punch 4 holes to let the wounderful aroma escape. Maybe the solo folks are making the cups cheeper not as thick.

Will keep doing maybe put small piece of aluminum foil under cup.
