... hot air soldering device.... I dont want something expensive.

I don't think there are cheap ones, I'd expect one to cost at least $500.

What can i use to clean this?

Isopropyl or ethyl alcohol or mild detergent, and a cotton swab.

Small portable gas soldering irons sometimes have a "hot air" attachment.
They can be picked up quite cheaply and run on cigarette lighter gas.

That and some solder-paste might get the job done.
