Very strong, and very good

We only get our rubbing alcohol from Sam’s Club , because it's stronger, and it gets the job done

Great for all purpose!

I use rubbing alcohol everyday for getting tough stains out, disinfecting, shampooing carpet, whitening my teeth or eliminating bad breath, etc. Love this product!

Shiny!!

We actually use this on our slate floors. We asked a professional flooring company that sells and installs marble, granite, slate, travertine flooring of all kinds and they told us to use alcohol on the floors so that the finish (top coating) is not washed off like with soap. Our floors shine like new and look like leather.

Great product!

Great product, not sure why there is 1 star review's. Your to review the product that's inside of the container not the container or it's cap. Some people just have no brains. This product is the great and I dare you to fine it cheaper than less then $2.00 a bottle that has not been watered down.

Be aware of Brittle Cap

This used to be good but the most recent purchase have very fragile cap. One of the cap was broken on the way to home, another one broken when I try to open it for the first time. Another issue with the new cap is that it has much larger opening than the old one, making is harder to dispense small amount of alcohol. I used cap from the old design and put one the new bottle, then it is much easier to use and also the old cap is much stronger. BTW, the old cap is white while the new cap design is transparent. I think the new type of plastic is much more brittle while the old white plastic is softer but stronger.

Great Value!

So glad Samsclub made this available for online purchase, almost impossible to find at the store. One of the bottles leaked a little bit in transit (cap broke), no biggie; pretty rough travels I guess. Having the seal made all the difference. Otherwise, more liquid would've been lost. Anyway, overall, happy with my purchase and will definitely buy again.

Excellent price during COVID pandemic

With shortages and price gauging happening to essential items, including isopropyl alcohol, it's great to be able to get this product at this price. Sure, it does go out of stock from time to time, but I haven't had any issues ordering what I needed. Bottles half this size are going for twice the cost at other retailers, and are even harder to find in stock. Thank you, Sam's Club!

not same for me

I had been using 91% alcohol for a specific cleaning/sanitizing task up until it disappeared from my area several months ago . The lower strength still required much soaking and scrubbing so I was glad to finally get a bottle in my hands .... unfortunately, it is exactly functioning like the 70%and I have tried both of the bottles in the pack . I am convinced this is package is NOT same as their previous 91%

It seems to have changed

I specifically need 91% alcohol for my line of work otherwise anything less will activate my ingredients. Before the isopropyl alcohol shortage of 2020 this alcohol worked perfectly. But now this product acts as if it's diluted and much more like 70% alcohol. I tested a spray from an old order and the new (both "91%") and the original performed as expected ( smelled of alcohol and evaporated quickly) and the new did not have much of a smell and did not evaporate much at all. Buyer beware if you specifically need 91% alcohol or higher because either the product is mislabeled or diluted. I hope this gets resolved!
