Subject: chemical precipitate

I'm looking for a chemical reaction (exchange reaction) in which two
aqueous salts are mixed to create a precipitate.

I want this to use simple safe household chemicals.

So the first opne I found: epsom salt and sodium hydroxide (Draino) is out
because the drano is too caustic.

Got any ideas?
