Magic Erasers In Your Pool

Have you heard of the new trend of putting Magic Erasers in your pool skimmer?

No? Neither have us.

Recently, a pool owner contacted us on Facebook to ask us about the legitimacy of Magic Erasers. Sure, I’ve used them around the house but never in a swimming pool. In fact, no one at INYO has come across this scenario either. So, we wanted to do more research on the Magic Eraser hype before we recommend it to pool owners.

How Did Magic Erasers Become A Thing?

If you come across the Magic Eraser phenomenon, you have Lisa Pack to thank. After a recommendation from her daughter, Pack decided to put a Magic Eraser in her pool skimmer overnight to see if it would clear her pool. Much to her surprise, it did. According to Pack, she placed the sponge inside the skimmer basket for 24 hours. By the next day, the green steps were crisp white and the water was crystal clear.

Soon after, her Facebook post went viral. News outlets, YouTube channels, and even Inside Edition interviewed Pack about her viral post.

Now, strangers and pool owners all over America are jumping on the Magic Eraser bandwagon.

However, the legitimacy regarding how effective Magic Erasers really are is still up in the air. How effective are Magic Erasers?

Magic Erasers And Their Effectiveness

Although we’d never heard of using Magic Erasers in a pool skimmer before, our initial thoughts were that it was too good to be true.

A mason jar filled with green water has a Magic Eraser inside. The cleaning product seemed to remove some, but not all the algae.As questions and comments began to flood the INYO Facebook page, our curiosity increased. In fact, so did the curiosity of several different service technicians in Florida. Andrea Nannini of Custom Pool and Spa Mechanics in Stuart, FL used the opportunity to test the theory behind Lisa Pack and the Magic Erasers. After a series of tests, the results confirmed what she and many of us thought, a Magic Eraser is not the answer to cleaning your pool.

To test it, Nannini placed a Magic Eraser inside a jar that she filled with green water. The Magic Eraser absorbed some of the algae in the water, however, it did not completely remove the algae from the water.

I should also note that Pack’s water was not very green. In fact, it was only cloudy. In all fairness, the Magic Eraser will work to eliminate some of the dirt in your water, however, only to a certain extent.

Not to mention, the Magic Eraser isn’t actively maintaining or correcting the chemical levels of your pool.

Magic Erasers Do Not Belong In Swimming Pools

Nannini plans to take her Magic Eraser tests even further. There is a chemical in Magic Erasers called melamine. One theory suggests that melamine, also used in CYA tests, might actually contribute to stabilizing your pool water. However, according to her research, if the water has CYA in it already, introducing melamine would create a toxic byproduct called Melamine cyanurate. Although her tests are not complete, the overall conclusion is that a Magic Eraser is not an effective product for pool treatment product.

To take things further, Nannini emailed the manufacturer about using Magic Erasers in swimming pools and the company replied by saying, “The answer to your question is no, we have not tested the products in pools, and the chlorine may react or interfere with the ingredients in the product.”

Well, there you have it, folks. We’re not sure why the Magic Eraser worked for Lisa Pack, however, like many pool regiments, what works for one may not work for another.

  1. I have used Magic Erasers to clean the sides of my white fiberglass pool..It works really well. But should I be using it??

    thanks

  2. My pool was not green when I opened it. But it was cloudy. We have been working for week to get it clear and have not had any luck. We have been keeping our chlorine levels goo and been skimming and vacuuming daily. Any suggestions?

        1. Check the PH of the pool water. You will probably need to add Acid (HCL).
          You should add a buffer amount of acid if your PH is above 8. (Approx 0.02 Liters per 1000 Litres (1 cubic meter) of water. Usually, Add acid in the Day and Chlorine in the Afternoon/Evening time.
          After the Buffer addition, then you should just maintain the PH at 7.2 on a daily basis.

    1. I had the same issue. Even using winter closing products I was having issues. I used 6 shocked, 3x the algaecide and let the pump run for a week using 2 shocks a day. Then I used a flocculant, vacuumed it up with the pump on waste, and then used a clarified. Its crystal clear now.

    2. I use clear aid after the pool is clean and just cloudy. It’s amazing. I maintain the pool weekly with the same product. Crystal clear all summer!

    3. Same issue I am having even had water tested everything was good idk what the hell it is. Blue as hell but so cloudy can not even see floor. Pump and everyrhing is working fine the filters are getting dirty n i clean or replace them. Do not get it never had an issue

    4. yes , get a 5 gallon h2o bottle drill several 1/2 inch holes on the bottom for water to drain……, get those cheap dollar store PILLOW, with POLY FILL //// then you hook up the bottle to the outlet of the pump, support the bottle on a pool ladder and let run for at 20 hours ….. depending on how dirty ur water is , u shouldn’t need to clean the poly in the bottle at all, just throw it away , the tighter the poly layers the better the filter, the more holes in the bottom. be sure to remove bottle from pool when you shut down the pump….. the pool water was crystal clean of everything, not cloudy, didn’t stink, no particles , the poly filtered everything for the price of the poly pillow I know it works i have done it my self periodically enough to know that’s the only way to filter, like a fish tank, on a bigger scale

    1. As a lifeguard, we always used Ajax for the tile edges that would get a bit of muck on them. Worked great, and never had a problem.

  3. After reading your article, your test is not accurate as you didn’t use it in the same method under the same conditions, so of course in no way are you going to get the same results. What i see here is a website trying to debunk something so people dont try new things that poasibly work in order to keep selling your pool products. Plus saying that Chlorine could cause a chemical reaction but nothing is said about the cleaning products used with magic eraser? Go back to the drawing board guys, you proved nothing.

    1. Those Magic Erasers have Formaldehyde in them for cleaning purposes, which when mixed with the chlorine that should be in the pool,will either cause a thermal reaction to make carbon monoxide and hydrogen chloride (the latter being a poisonous gas) and when that thermal reaction is exposed to sunlight it becomes phosgene (another poisonous gas)

      It’s not so much trying to debunk something to keep selling pool products, it’s simple science so we don’t gas more people to death by accident. That shit already happened in the 40s.

      1. I have used magic erasers for 2 seasons in my pool now..no gasses or chemical reactions. I put 4 small squares in my skimmer basket and it helps filter and keep water clean. Used way less chemicals than normal. I recommend and highly suggest using magic erasers..Seems safe to me..I have a lot of friends that have pools and they have been doing the same thing for years. Just one man’s opinion..

  4. It’s working in my pool & quick too! Now my pool was cloudy. I did the start up kit but no water clarifier yet. I’ve had a pool all my life & it never got this clear so fast! I’ll take it out soon as the pool is ready to go & try it again thru out the summer!!

  5. Ho, I just have one question and that’s how to remove stains from the bottom of my pool? It’s been stained for a bit over a year I say? My mother thought the magic eraser might work but I thought it was too good to be true and I was a little bit right? I just wanna clean the stains off the bottom of my pool is All.

  6. The “magic eraser” is just a type of foam insulation that works are ablative sandpaper. It’s not going to magically clear the pool water just as it won’t magically clean your tub if you just set it over the drain as you take a shower.

  7. We’ve tried it and although in the pool I couldnt tell a huge difference, the eraser was pretty greeen when done, We took the tablets out of the skimmer. The formaldehyde content is a non issue, I believe the companys response. I have a 40,000 gal pool, so I dont think the little eraser is gonna cause me to grow a 3d eye or anything like that. Its worth a try, not a biggie either way. Thanks for all these scientist with their post on here

  8. This is the first year we’ve used the Magic Eraser in our pool and it absolutely works. We’ve had a crystal clear pool all summer with little or no maintenance each week. We keep one in the skimmer at all times (have only used two all summer).

  9. I’ve used the Magic Erasers all summer, and this is the first year I hesitate to close the pool for the winter, because it looks fantastic! I have a 36,000 gallon pool and use one eraser in each skimmer. Crystal clear, always balanced.

  10. I’ve had a completely different experience. My indoor vinyl pool had clear water before I began using Magic Eraser. I was using it to scrub away stains or oily marks above the water line all around the whole pool. The marks didn’t totally go away, but dramatically improved & I thought I had found something amazing. Given a few days, however, the pool water started turning green!! When I checked the skimmer there was this gross tacky green slime all around the edge. Absolutely disgusting!! Had to use multiple paper towels to wipe this goo away. The water is still green tho, even after a full scrub/vacuum & later my once a month muriatic acid treatment. I suggest sticking to the old ways. Later I checked the packaging & it said ok unless mixed with Chloride….well guess what’s in my pool water! Now I want to know what chemical reaction has happened, what’s it done to the pool water & my plants, not to mention myself. Ok “scientists” have a run at my experience….

    1. you are right… the pool is not a hole full of water clear or not…
      it is a hole full of chemicals, even water is h2o, bacteria, viruses, protozoa, fungi, pollen, they are all living elements that are looking for the opportunity to grow and become stronger, any change in the chemical even for minutes can lead to disaster … unforeseeable and unfathomable disaster. most of the time we have good luck … imagine that the legionella is in your pool, it does not grow because you have balanced chlorine and pH, at one point you put something that ends up making a chemical reaction, the bacteria takes advantage to grow , well even without being in the water, you can get sick from legionellosis and 30% chance of dying.

  11. I feel like some of the success I have seen people get online from magic erasers could be from increased filter effectiveness and not necessarily just having the magic eraser in the water. Having water pulled through the magic eraser by the pool filter probably provides different results that just putting the magic eraser in green pool water. It would be interesting to compare a typical cleaning sponge vs a magic eraser in the pool filter.

    1. Will try both plain and magic eraser. Now I am curious to. I think we may need to change the sand in our filter.

  12. No offense but you sell pool treatments so obviously aren’t going to endorse this product.All I know is I have tried everything this year to clear my pool and nothing would clear it up.And yes I tested,balanced,shocked,vacuumed,brushed and ran my pump and filter more than enough!Last night my pool was cloudy blue but you couldn’t see the bottom.I put one magic eraser in it and went to bed.Today the water is crystal clear and looks perfect.I am definitely sold and will swear that the magic eraser works!!If you just have cloudy water,not solid green, try it and I promise you will be amazed by the results.

  13. Well I just went to get some. I have had perfect levels even went to test water at pool town just in case and they said everything was perfect. I can not see the floor but it is so blue but so cloudy. I’ve scrubbed and vacuumed the walls always cleaning or changing filter pump and everything works and this has been going on since memorial day. I will take pics before and after and will let everyone know if it works. God i hope it does.

  14. Hello,
    We are having an issue with high chlorine 5-6 ppm and very high CYA. We partially drained and refilled and CYA was down but it was green. So we used Clorox Algae Eliminator. After 12 hours of constant filter running, changing filters as they got green, CYA is back above 150 chlorine is still 5 ppm and still green.

    Should I just try to address one problem at a time? Get the CYA levels down and maintained and then worry about algae & chlorine level?
    We’re at a loss!

  15. I wouldn’t leave one in the skimmer basket, but how about using a Magic erase sponge to scrub stubborn dirt spots on a vinyl liner?
