Can you bleach then reuse a 2 part mechanical filter?

Just wondering if anyone could shed some light on an idea that maybe possible. I see people bleach/wash their filter socks. Instead of paying $15 for a box of 3 mechanical filters and spending $10 in gas to drive to find these. I have a few questions

One side of the mechanical filter is a foam. The other is a polyester fiber.

1)Would bleach cause a chemical reaction with either side? (One side is foam. The other is a polyester fiber)

2)Would this be a very bad idea?

3)What parts of bleach to water ratio if I was to do it?

4)How long "IF" I was to bleach it would you suggest letting it sit to air dry or let it soak in water or both? (After pulling it out of the bleach/water solution to clean it.)

Here is a few pictures of the FLUVAL C4 mechanical filter.

I would think bleach would be ok, but I'm not sure how it would hold up over time. Would it be possible to just use filter floss like this https://www.amazon.com/inTank-Aquar...8&qid=1538686546&sr=8-3&keywords=filter+floss in its place? Much cheaper and free shipping.
