That's my hardtop, i would think its pretty impossible to recover the inside of a soft top, cleaning it would be the only way i think.
If you mean the hardtop, you have to take off the front clips, and the 3 push in ones across the rear, and gently take off the thin fiberglass sheet or ''biscuit''. Then you take off your old fabric, get a stiff brush and brush off the thin layer of foam (very messy do it outside!) and then get some spray glue and material of you choice to recover it. only help with that i can give is take your time.
