Question: After installed, what is the best way to keep the bath tub clean?
Document: That is why I have gone through 4, and you can do the math, it's a little expensive to keep replacing. One time my housekeepers pulled it up to clean underneath, because they didn't know any better. However, the other 3 started becoming unattached and floating when my son was in the tub. We are currently using a suction cup mat, and I absolutely cannot stand it. Glad I found this on Amazon; it is a definite must have over the other bath mats!
We have been using this bath mat product for over 7 years now (I haven't been able to find it until now on Amazon, but I have had 4 of these mats over the past 7 years). We originally got our first gatorgrip bathmat when a childproofing company came out and installed it. It is easy to clean, stays put, and does not grow mold! The only problem that I can find with it is, once it starts to peel up, it's time for a new one.
We LOVE this mat. We have 11 month old twins - when it was time to take them out of the bath ring, we were very nervous and very cautious during their bath time because of course they like to move around in the tub. We installed the mat after a thorough scrubbing & rinsing of the tub, walked on it a few times, and left it a couple days to &#34;cure&#34;.
I often have bathtubs refinished at properties I manage. When tenants use the suction cup bath mats, sometimes the finish (tub paint) will come up off the bottom of the tub, which usually means another refinishing job. So, the last time this happened, instead of refinishing the tub again, I installed this Gatorgrip Non Slip Bathtub Mat. It was big enough to cover over the bad areas and it is a totally good enough item to leave permanently installed in a bathtub.
My 13-month old daughter insists on standing in the tub and before we installed the Gatorgrip, it was a scary scene with her slippery little feet sliding all over the place. Now with the Gatorgrip in our tub, she can stand (with supervision!) and doesn't slip nearly as easily! Plus, it's made in the USA which was a big factor in us purchasing it.
I already have part of my textured shower floor covered with this mat. It is the only mat that is truly non-slip that also adheres firmly to my textured shower floor that I have been able to find. I ordered the tub mat and plan to cut enough to cover the rest of my shower floor and have some in reserve for an area that might need replaced after time. This mat is also the only mat I have found that has a truly non-slip texture to keep one's feet secure.
If you have a textured tub you have NO other option but to buy this. Our child (12 months) cut right near her eye from slipping on a suction cup type mat so we didn't hesitate to buy this once we found it on Amazon. ZERO slipping in the bath now!
I wasn't sure about purchasing this mat but glad I did. It is easy to clean and very durable and easy to install.
I have tried every kind of shower mat (including rubber), & researched them all for my elderly mother. Even tried to find a similar one to save $. This works so well that I ordered one for myself! Easy application, even if you have to cut. This thing WILL NOT come up, even around edges. No slimy residue underneath to ever have to clean. Very comfortable on feet.FINALLY HAVE PIECE OF MIND ABOUT MY 88 YR OLD MOTHER IN SHOWER.
We now have peace of mind that the twins will be able to enjoy their bath without so many unnecessary slips & falls, and so will we!
Answer: I just spray it with scrubbing bubbles cleaner and take a soft scrub brush to scrub it.
