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.
