Does a capacitor remove DC offset?

No it does not remove DC offset - it allows there to be a DC offset. A capacitor blocks DC because a capacitor does not pass DC and it allows there to be a DC bias over the capacitor. It has infinite impedance at DC. And so it passes AC as it allows AC currents through and has low impedance at high frequencies.

What is the difference between inner foil and outer foil of a capacitor?

Basically, most of the capacitor, has what we call the inner foil and outer foil. Because, most of capacitor’s construction is based on the winding of paper or other conductor (silver, copper, gold, etc), so we will have a start position (the inner foil) and the finish position (the outer foil).

Can a DC offset be dropped across a cap?

@Kartman sure that makes sense, but going back to the DC offset for a moment, suppose there is some DC offset between two grounds... Connecting them with a cap would provide infinite impedance between these grounds, so any DC offset between them is entirely dropped across the cap.

Do capacitors remove DC bias?

I know that capacitors remove DC bias on a signal, like with an AC signal being output from an amplifier; just couple the signal through an HPF and you're left with the AC signal oscillating around 0 V. Does the same principle apply to two grounds that might have some DC offset?

What is the difference between a negative side and outer foil?

The negative side = outer foil is identified when the side is connected to the positive test probe. The side which has higher noise = the outer foil (it captures the interference more). This negative side = outer foil should be connected to the nearest ground.

How are capacitors made?

These capacitors are typically made by taking a long narrow strip of insulating material and placing a strip of metal foil on both sides of it. The two pieces of foil become the plates of the capacitor, and the insulator is the dielectric.
