How to use sunscreen

I don't think I usually finish using sunscreen once I buy it.

Leftover sunscreen like this is effective for removing stickiness.

Like the stickiness of a sticker on a bottle or the spot where packing tape was applied.

There's still stickiness from the tape left on the scissors, you know?

It cleans well if you wipe it with a dry cloth soaked in it.

It's also great for removing sticky residue from flyers stuck on doors.
