I am getting into the new refurbishing style with the machines and I was wondering after polarizer removal can the LCD sense my touch or can I test to make sure that the ribbon cables weren't damaged while cleaning?

Only one way to find out.
I've never removed the polariser, just the glass, and it works with no glass, that's all I know.
Pretty sure if you remove the polariser, you'll struggle to see the screen?
Out of curiosity, are you using LOCA or the OCA sheets?

OCA. I was going to put a polarizer over so I can see and test the LCD.
The short answer is yes, it can.
The long answer is: There is no way to tell until you apply the new polarizer. You would need to plug the LCD into a phone or tester with the old POL removed, but a display without a POL is just bright. There are no images. In theory if you had an LCD tester that tests digitizers, that could work. I own the $700 multi-iPhone model and the thing isn't anywhere close enough to reliable when testing digitizers to depend on that for sole testing.
You have to put the new polarizer on to be able to touch, swipe test lcd function, they are not expensive, you usually do not have to replace pol unless original is quite deeply scratched. You need to make sure you get quality supplies otherwise you will be struggling. It is pretty easy and it is all trial and error.
You need to find the right equipment for the job, if you are pumping out screens without autoclave machine and no bubbles you are on a winner. Need the right equipment

your supplier should put you through full training, if you have bought the machines without training then expect 6 months of a high fail rate. A colleague of mine went through this, its a serious art / technique.

I hope he went to China and learnt it there because it's the best way if you have a friend that is a supplier in China.
Otherwise more time spent learning than needed I guess.
Supplier training? I feel lucky to just get the correct part out of China.
