So I really enjoy my ice cold lemon water. I think it's just tops, and tend to squeeze in 3 or 4 wedges in my glass. Well at work, our breakroom generally has either plastic cups (i.e. Solo) or styrofoam. I've noticed that when I drink my lemon water, the lemons seem to melt part of the cup!

If I still have juice on my hands when I touch the styrofoam, bam, an imprint of my fingerprint is melted into the cup. And the solo cups seem to have two layers, the red outside and white inside. I'll see random spots in my cup where the white has been melted away to reveal the red, spots that definitely weren't there before.

I know the solution is probably to switch to a real, reusable glass, but I'm wondering if I should be concerned 1) about the plastic debris I've apparently been sipping and 2) if that amount of lemon is melting my cups, could it be doing harm to me?

Well your system wasnt design to digest plastic so I suggest getting a non permeable glass to drink your acid water. LOL

That can happen, as you have found out! If you were to add just a shot or so of vodka or gin into the water and lemon it would stop that from happening.

Odd, I found a 1979 newspaper article that mentioned something like this, and it mentioned that styrofoam cups had been around for 25 years at that point. 33 years later they're still being used and there are very few references to such a problem, and a few mentions of chemists saying lemon juice can't possibly harm styrofoam. So I doubt that it's a real problem.

What I think is really going on is that some cups, especially cheap ones, are just prone to be porous. I've styrofoam cups that oozed water, oozed coffee. You just happened to notice it with the lemons and mentally associated the two.

I actually had lemon juice on my hands one time while using a Styrofoam cup with tea in it. It actually ate away where my fingers had been on the outside of the cup. When I took my hand away, you could clearly see indention's on the cup. Freaked me out.

Let me add, I've used lemon in styrofoam cups before and never had a problem. It probably was some kind of extra cheap cup or something.

I had a thought... citrus oil is a solvent, and is used as a commercial degreaser. I wonder if it might actually be the oil from the peel causing the mischief?

You know, that's possible for the solo cups, at least. I noticed this last time that one of the peels had a little pink spot wear it was touching a spot that was worn through. Maybe I should conduct a little experiment with the two types of cups and press the juice and the peel against them, see which causes the deterioration.

So, did Dorothy throw water/lemon on the wicked which was she made of styro-foam as she melted well away.

I do love lemon water and I guess it helps to degrease my system...

I cut up a whole lemon and put it in a jug of water. The lemon ate away at the plastic jug.. So if it can do that then I wonder what it does to our bodies

Why? Our bodies aren't made of plastic.

You do know that your stomach has hydrochloric acid in it, don't you?
