In a word, NO, Woolite is not an All-Purpose Cleaner replacement. It is good for leather cleaning, as it was recommended at one time by GM, (according to Scottwax). I think there are better leather cleaners a true Autopian can use, but if it works for you, use it (and it's "less expensive, cost-effective, per application"). Another cost-effective cleaner is LA Totally Awesome sold at Dollar General. For a cheap cleaner, it works pretty good. Not so sure its an APC or its "safe" enough for coated leather, though.
Pellipe, I would also suggest NOT using OPT Power-Clean on fabric seats or carpets. The fragrance is less than pleasant, in my opinion, after it's absorbed by the fibers, and lingers for days, sometimes weeks. It's a great cleaner/degreaser for hard surfaces, like painted metal, plastics, or rubber tires. A more pleasant-smelling APC is Meguiar's Detailer Line, D101 (the foaming green stuff) to use on carpets and fabrics BY HAND with a brush and microfiber. Their D103 (APC+, a non-foaming formula for carpet extractors) is no longer available, as they have replaced it with a carpet cleaner and specific stain-removal formulas.
