Rickie, are you using this for a prespray? I looked it up and it says for hard surfaces? Nothing about carpet?Enzibrite by MPC; dwell 20 minute after prespray. Very inexpensive; Smells like popouri for up to 3 weeks after cleaning. This stuff beats anything I have seen hands down. If you get balck top tar; follow with Orange Solv and a nuetral rinse.
