This is being written as a stand alone Thread, but the topic is also being discussed, and some of my info here is also in the other particular Thread as well. http://www.troublefreepool.com/threa...a-houses/page4
The OP of the linked Thread above has left a message on the topic on the Magic Eraser web site, and is awaiting their answer too. So hopefully, he will include the information he receives in the comments of this Thread, as well.
Here's how the Questioning began: Earlier today I was going to suggest that a Magic Eraser may be useful in a pool to remove some dark marks on the bottom of the pool. But then I got to thinking I wonder what the heck is in the Magic Erasers, and do they like to play nice with the bleach that I know is in there already. So before I suggested this as a possible solution to removing something from the bottom of the pool, containing chlorine, I set of to find out for sure IF they are SAFE to use with the bleach in contact.
I've heard so many people say how beneficial they are, and how well they work in cleaning about anything, pool stuff, included. The magic erasers work well on areas with hard to remove marks on the outside of the pool. But are they really safe?
Here is what I ran across so far: I've found that outside the pool Yes, in direct contact with the bleach, however, is not advisable.
There is actually no active ingredient listed on the box of Magic Erasers which I noticed when checking on my box here. So I set out searching for answers to ensure there would be no chemical reactions between the active ingredient in the Magic Eraser, and the bleach in the pool.
Turns out Magic Eraser wasn't originally even made to clean, it was made as an "insulator/fire retardant" that just happened to end up also being an excellent cleaning tool too. Also it Turns out there is no active ingredient on the box because there is none in the Magic Eraser itself. According to the article linked below the "active ingredient" if you want to call it that is merely Your "elbow grease."
I'm thinking ok no active ingredient equals no chance for a chemical reaction, Right? Wrong.
It does turn out however that the Magic Eraser itself "is made of a formaldehyde-melamine-sodium bisulfitecopolymer foam made by the German company BASF". http://www.kitchenandresidentialdesign.com/2010/06/whats-in-magic-eraser.html
According to this article http://www.themodernembalmer.com/bleach.html as well as, several other reviewed. Formaldehyde, and Bleach should Never be in contact with each other.
So the question remains is it really SAFE to use a Magic Eraser in your pool, on your pool equipment, when it will be contact with bleach, or not?
Is the percentage of Formaldehyde too low in the Magic Eraser to actually be a risk?
I suspect (just my thought so don't take it as fact) that for cleaning around the top of your pool as long as your rinse well to remove all the small Magic Eraser particles left behind the risk would be slim to none.
But if your plan is to use it to remove the ring within the waterline of your pool, or marks off the bottom of your pool containing bleach, that your risk could be significantly increased.
Anyway, that's what I've located thus far and will pass along any additional info I locate. But from a safety aspect, and wanting to ensure all my new TFP friends, remain safe at all times, I felt it important to pass the information along.
Anyone who has anything else to add, please feel free to do so. I look forward to reading the comments regarding this. Have a wonderful night .
