That's easy to remove. It would be really sad if someone slapped some etching cream on the lense though. That's a non-removable, chemically permanent change to the glass.

    Causes severe burns that may not be immediately painful or visible.

    Our chemistry teacher warned us about this stuff. She told us that if you get it on you, don’t hesitate to call out immediately because you will not feel anything and think you’re okay until it’s too late and under your skin. And then it burns. So, so much worse than if you had washed it off right away.

    Plus it'll dissolve your bones faster than your flesh

    I used this in 8th grade to etch glass for art class.

    It's not as bad as all that. Just wear gloves and if you get some on you, just rinse it off.

    It won't start dissolving your flesh or anything and needs time to even etch the glass.
