Moe ~ what brand of products do you use? I use Melaleuca products, which are environmentally friendly, and they work FANTASTIC!! My husband works with automotive chemicals all day and when he showers, the chemicals all end up coating our shower floor. We live in a newer home and I noticed after a while our shower floor was turning grey EVEN with scrubbing it regularly with Soft Scrub. I joined as a customer with Melaleuca to have safer products in my home for my son. The first time we used the Tub & Tile, we were AMAZED!! Our shower was COMPLETELY white again and now the chemicals don't stick like they used to! It has also taken off any and all hard water spots. I love their products! One of the things I like best is that there is NONE of that horrible, choking smell you get from the cleaners that contain toxic chemicals like Tilex, CLR, LimeAway, etc. You do have to join them as a customer, like you would a Sam's Club or Costco, but the membership fee is only $29 and you just agree to buy 35 points worth of products per month to get the preferred pricing (it averages out to about $40 - $60 per month). 35 points is very easy to do as each product has it's own point value, some as small as 2 and some as large as 42. I buy about 75 - 100 points worth of products a month. They carry all your everyday items like bath and body products (shampoo, deodorant, toothpaste, soap, etc.), nutritional and vitamin products, skin care and cosmetics line, laundry and cleaning products, over-the-counter pharmaceutical products and baby/kids products. You can only join through a current customer, so if you're interested, let me know and I'd be happy to help get you signed you up. :)
