If you have a bathtub with a slip-resistant bottom that no matter what you use to clean it, it still looks dingy, grungy and downright grimy, today I have really good news and at least one sure-fire solution that will bring even an older tub bottom back to clean, like new!

Since the Americans with Disabilities Act became law in 1990, all bathtubs must be manufactured with some type of anti-slip bottom. Kohler porcelain tubs come with its patented Safeguard Slip-Resistant Surface, which has a very distinctive look and seems to be the most prone to this ugly problem.

The problem is not only with Kohler tubs but with any manufacturer who etches the tub’s bottom to provide the non-slip feature. That encourages the oil from your feet to start staining the tub’s bottom. Then it’s like these stains get embedded and locked in forever.

I’ve heard from many readers who have tried everything they can think of to remove these stains, without success. In fact, all of those efforts seem to do just the opposite, eventually making the problem even worse.

Some readers have reported using Magic Eraser, Bar Keepers Friend, Zud and Comet, all with varying levels of success. But you need to know that Kohler warns against all of them because they can harm the anti-slip and porcelain finishes, possibly creating an even worse problem over time.

Kohler recommends only three products to clean its Safeguard Slip-Resistant Surface:  ROG3 Bathtub and Shower Cleaner, Clorox Disinfecting Bathroom Cleaner, and Tilex Bathroom Cleaner.

ROG3 Bathtub and Shower Cleaner is the sure-fire product I mentioned above. It works on even the worst problem, and I cannot say that for the Clorox or Tilex. ROG3 is the #1 product recommended by Kohler for its non-skid and porcelain finishes.

ROG3 is miraculous and will bring your tub back to its shiny new self including the slip-resistant etching, without damaging the porcelain or the anti-slip surface. You must get this product (actually it comes in a kit) from the manufacturer’s website. ROG3 is not available in stores or through Amazon.

Pssst! It’s not too late ...

In the kit you will receive two bottles—ROG3 Blue Liquid and ROG1 White Cream plus a scrubbing pad and sprayer head, for about $55 plus shipping, which is quite a bargain as compared to having a tub refinished or replaced. Look for a discount and or free shipping option at the ROG3 site. Often the company will offer that at least for a first-time purchase.

The kit will come with full instructions, which are quite simple. I suggest that you take a few minutes to watch this online video that will show you exactly how to use the product to wash all of that ugly stain down the drain. Then read the information on the ROG3.com site.

While ROG3 Bathtub and Shower Cleaner is a Kohler recommended product to clean the slip-resistant bottom of its bathtubs, it is not limited to that. This product will clean all tubs and showers—porcelain, fiberglass, cultured marble—howers, tile, Formica, Corian, stainless steel, toilets, sinks and grout of dirt, grime and build up—those challenging situations that need more than a miracle!
