My company has used this product for four years now and we have never had a problem with it. It does a great job of melting even at low temperatures. We have also used this on both new and old concrete and we have never had a problem with flaking or pitting concrete. I would highly recommend this product to anyone. I think that other comments that have mentioned issues may be applying too much at a time.

The website is very misleading. There is nowhere on the website that it indicates this product is mostly sodium chloride aka rock salt. The listing mentions calcium chloride and magnesium chloride which are much more effective at lower temperatures. It does contain some calcium chloride and magnesium chloride but a small amount of each. I would not have purchased this if I realized what I was getting as you can get the better products for a little more money but they are much more effective. Sam's club can do better than this.

First I want 2 explain why the review from Missouri is suspect...all concrete not properly sealed will flake or become damaged over time with any salt exposure. That being said, this product is the best value that I have ever used. I'm in the snow and ice removal business. The combination of calcium chloride and magnesium chloride at this price point is the best I've found...the size of the particles is smaller than traditional rock salt and easy to spread.

I refrained for many years applying any ice melt products to my concrete. Against my better judgment, I applied Miracle Melt as directed. It states on bag "safe for concrete", clearly it is not. After removing the slush as directed, the chemical compound refroze and created a large amount of spalling to my smooth concrete. Spalling is the effect left behind when the smooth surface is eroded, leaving the rocky layer beneath. I returned the product using the Sam's Club app, and they said don't return unused or unopened bags to store. (So I disposed of them in the trash.) I based my purchase, as most do, based on the glowing reviews on the Sam's app. So I felt it was imperative to warn others with my own review. I made multiple attempts to publish negative reviews warning them of the possibility of Miracle melt damaging their driveway, none were posted. I assumed this was a violation of ethics and contacted Sam's. They requested the URL and email address proof of published rating, of which I had none because the app fails to do both. I am now coming to the realization that the app is worthless and defective when it comes to publishing reviews. To my understanding, when I wrote and sent the review, it was complete. It wasn't until I came to my actual computer to search for the URL, that I realized I should be getting a receipt email for my review. This is a flaw that will likely dissuade most customers from stating their opinions. (Because they have to do so from a laptop or personal computer.) A mistake/flaw that will likely cost me dearly in damage to my driveway. Would also like to add photos, but this feature is disabled.

Magnesium chloride .. Look it up on internet (terrible for cement damage). Tested on asphalt driveway will not put on my cement! Put 3 times as much on driveway as my usual brand.. Very poor ice / snow melting at +8F with 2x application then applied 3x. Calcium chloride is the best ice melt work at -25F and least damage to cement, also most expensive. This product appears to be mostly Magnesium chloride and a little Calcium chloride.. Cheap and good for light ice at warmer temperatures.. Miracle Melt about $9 / 50 lb.. Calcium chloride about $20 / 50 lb. You decide whats best for your application.

I just found this product at the end of last year's snows and am just now starting on my 2nd bag. So for those that are experiencing concrete decay, I think maybe you should rethink your application. I only have about 30ft of sidewalk, but often overlap my application on my neighbor's portion and only use about 10-15# at a time In 4-5 applications since last year, I have experienced NO concrete decay and this stuff works great even when the temps remain in the 20s and single digit windchill. This last foot of snow we got in 5hours, it kept my sidewalk clear of ice for 3 days after I shoveled

The bag is mostly dust, or the pellets are too big. I used up 50 pounds in only two days because of that. The dust flies away with the wind, and the huge pellets fall too far apart, and they stay solid, so the snow melts only around them in tiny pockets. My drive looks now like it's covered with polka dots. Not a good product. I bought this brand long time ago, and it was bad back then, but not this bad.

Nothing beats this product, at the cost per bag the outcome is the best. You can hear it working immediately after applying no matter how much ice. Application amount is minimal and consistent applications allows for best results. Keeps our customers happy during the winter months. Not a harsh chemical even for the animals due to its quick dissolving action.

Too much salt. Will not work well below 15 degrees.

Works well. Icy sidewalks melt quickly
