After replacing my digitizer, I proceeded by wiping the lcd with a microfiber cloth. I think I wiped a bit too hard and there are faint white spots when displaying something with a black background. Is there any way to fix this?

Those could either be pressure points meaning something is under the screen pushing up on it or it could be a defective LCD. If you can get that screen off in one piece as those spots disappear then something is putting pressure on the display. If they’re still there when you lift the screen off then it’s a defective LCD and you should contact the supplier to get a replacement or refund depending on their policy.
