I have used almost every shoe cleaner on the market. Shoe Magic, Sketchers, Shoe eraser, Oxi clean, Soap, Dawn, Mr. Clean, upholstery cleaner, Leather Cleaner, Tide, White wall Bleach, Armor-all, Kiwi, Grandma's, and more I have forgot. Half of them like magic cause the leather to crack over time. A lot of them cause yellowing over time.
Bottom line, Shoe doc thus far. Is the BEST shoe cleaner I have used hands down. You know it conditions the shoes. When I am done cleaning my hands feel softer. That tells me this cleaner does what it states.
I clean my shoes at least once a week. I spot clean them about every other wear. About once a month. I do a deep clean. Removing laces and cleaning inside n out. This is on my M-Thu seekers. My Fri-Sunday. Almost same routine. Just a deep clean every other month or so. I am an old school. Keep your shoes clean!. No matter how mush they cost. From the Prowing days. Now my soles wear out and the shoe still looks Good! Love this product. Recommend it to anyone who likes clean shoes.
