Question: how do you clean an aqua rug
Document: Do not believe that Aqua Rug will stay mildew free! Pouring mud on it? Really?! I have tried everything to clean them and the mildew is on the inside and cannot be removed. The suction cups are a joke too. I live in Nevada and we have no humidity. Can't imagine living in 100% humidity with these rugs. Don't waste your money. They also take 6 weeks to ship.
Bought a second Aqua Rug as switch out. Tried to clean by soaking in bleach + Era + water and got  reddish brown stains (could be from iron in our water or chemicals in Era)? Also had some black mildew? in spots where we stand. Just an overnight soak in bleach and sunlight to both sides [three or four hours per side) leave the mat clean, scum free and smells pretty good.
the package didn't say Aqua Rug but it has the same features,
The Aqua Rug is nice to stand on, but the suction cups don't work in my bath. I wish it were larger.
I had to have an Aqua Rug a couple of years ago in my old house and they worked perfectly the only reason I got rid of them is because they just started looking grungy.
I was going to purchase Aqua Rug. I'm glad I saw the reviews from customers. It is a plus to search for reviews on this product. Thanks customers, you save me money..
In replaying the Aqua Rug video on the Aqua Rug website, the product I got did not look exactly like the Aqua Rug in the video.No reflection on the actual Aqua Rug product is intended, here, as I did not get the actual product, so I don't have that product to make a comparison against.
The product I received was not the Aqua Rug product as seen in the commercials, but an imitation. It was titled Drain Away Mat and is apparently made by a company titled Handy Trends and not the Tristar Products Inc. as the Aqua Rug website indicates manufactures or produces the actual Aqua Rug.
The Aqua Rug is being marketed with lies and falsehoods. The product is advertised as not requiring any suction cups and will stay in place in your shower. Not true, the AQUA RUG comes with four suction cups affixed to the rug, however they will not adhere to a textured surface which is very common in today's modern homes. Their advertisement neglects to point this out and for the obvious reason that they do not wish to provide a FULL REFUND.
It took a long time for me to initially get my aqua rug -- probably about three months. I like the aqua rug because I don't get mildew build-up underneath it; however, it definitely stains. I have mildew build-up on the actual rug in the corners. I have tried to wash it in the washing machine but have not been able to get rid of the mildew. As far as slipping, it doesn't slip but definitely does move.
Answer: Don't clean it, just throw it away!  I tried to remove the mold that was advertised NOT to form on it and bleach didn't even touch it!  Don't buy it!!!
