—Look at the note below.—You will hear a talk about a cleaner.

A: Tell me about this new cleaner please. Can it be used to clean metal?
B: Yes, on certain kinds. It’s very good on aluminum and brass.
A: Aluminum and brass. I see. What about other metals? Can it be used with silver?
B: Well, it’s not really very good with silver. We have a special cleaner for silver.
A: Oh. And what about enamel surfaces, like on a bathtub, for example.
B: Yes, it works weft on enamel.
A: And what about on things like floor tiles?
B: Yes, it’s perfect for floor tiles. It really takes off tough stains and marks. But it’s not good for cleaning wooden floors or wooden surfaces. It might even damage them.
A: How about plastic?
B: Plastic’s fine. No trouble at all.
A: Good, then I’ll take two cans, please.
