92 Legacy Interior Cleaning

Good Morning,

I have a question about cleaning the seats and carpet of my Legacy. We just bought the car and it has been sitting for awhile.

The back seat has some kind of Rust stains on it that we tried to get out with cleaner and it faded the stains some but did not remove them. Also, since the car has been sitting it had some moisture on the inside and the floor carpet is stained and I am not sure if it is mold. The car does not smell as bad since we cleaned the seats some, but this morning I noticed that the smell is still there.

Can anyone recommed what I can do to clean the interior aside from buying seat covers. I would like to try to get as much of the stain on the back seat out as I can, then I will revisit the seat cover issue, also how can I clean the carpet and get the car to smell at least halfway decent. Right now to me it stinks and driving it is not fun.

Thanks
Thembi
