Acrylic maintenance question

[PufferCorps]

Hello Fish Bro's!

What do other acrylic people clean with?
I'm currently using that magic eraser to clean the walls once a week, but it seems like my tanks look kinda hazey. I think I've got some salt residue or using the eraser has been scratching it.

Is there something better for cleaning acrylic? I was wondering if I could use the super ultra fine grit sand paper for weekly maintenance and gradually bring the acrylic back up to ice cube clarity.
Has anyone tried this? Is it safe for the fish?

Thanks in advance!

Longtime no see!
I would be wary of using sandpaper as I feel it would scratch the acrylic, as far as cleaning acrylic I like useing washcloths a lot, use it every few days, especially near the water line, this prevents calcium/hard water build up , which is hard to remove once it really builds up
