AntiFreeze for Pool Closing (Ethyl Alcohol)

[richmgreen]

For closing the pool this fall I always use pool safe anti freeze. I saw this at Home Depot for a fairly low price. Says on bottle that it is safe for swimming pools. But the description says …. 128 fl. oz. Ethyl Alcohol -50°F Universal Non- Potable RV Antifreeze. Is Ethel alcohol safe to use or should I spend more for alcohol free. ? They have it for $3.98/gal vs $7 plus.​

Thanks
Rich

@Donldson can confirm, but I believe the alcohol is just a sub-ingredient of antifreeze products. As noted in the SDS, Propylene Glycol is the main (correct) ingredient. It should be fine.

Do you have a link to the product?

Ethyl Alcohol (Ethanol) is the type of alcohol that people drink, so it should be safe to use in pool plumbing.

Propylene glycol is also considered to be safe for the purpose.

I did not know that ethanol was used for the purpose, but it seems like it was made for this.

I agree, should be fine.

They are supposed to be color coded so the pink stuff should always be safe for pool use, but having a friend working on getting his pilot license and learning about the mess that fuel coloring is I don't take these things quite for granted any more.
