Questions & Answers about Al limpiar la cubierta, los dejé en la popa.

How exactly does al limpiar work to mean 'upon cleaning'?

The contraction al (which is a + el) followed by an infinitive like limpiar is a very common temporal shortcut in Spanish. It translates to 'upon doing an action' or 'when doing an action'. It replaces a longer time clause like cuando limpié (when I cleaned).

Since limpiar isn't conjugated here, how do we know who is doing the cleaning?

In the al + infinitive structure, the person doing the action is almost always the same as the subject of the main sentence. Since the main conjugated verb is dejé (I left), we automatically know that 'I' am the one who cleaned the deck.

Could I attach the pronoun los to the infinitive, making it al limpiarlos?

Yes, but it would change the meaning. If you said al limpiarlos, the 'them' would become the things being cleaned. In this sentence, the deck (la cubierta) is what was cleaned, and los refers to separate items being left at the stern. Therefore, los must go with dejé.

I've seen dejar used to mean 'to let' or 'to allow'. How do I know it means 'to leave' here?
