getting security deposit back in South Carolina

[Stas Vernon]

Hello,

I am trying to get my security deposit back. I cleaned the apartment very well upon move-out (I've spent a lot of time cleaning and left it in probably better condition than in when I moved-in) and there was no damage (the rental agency doesn't even claim damages in move-out charges list).  I also provided cheque for professional carpet cleaning to them.  I have made photos/videos upon move-out so I believe I can win the case as there is nothing that I didn't pay or violated etc. 

But I have no idea which charges are legal and which are not... which forms to use to submit the case to small claims court. Actually never been to the court before so don't know where to start.
I already tried to settle the issue by phone/email.

The the rental agency listed the following charges in move-out inspection form:
1) Apartment cleaning
2) Turn on water for cleaning (city charge)
3) Stove drip pans replacement

I don't agree with any charges and believe that at least the 2nd charge is simply illegal, but how to prove it in the court?

Are these charges legal in SC?

Are there other ways to get deposit back from  the rental agency besides small claims court?

Any even very basic advise will be useful for me. Please don't assume that I know smth b/c it is very common. Thanks!
