Purity of "Instant Power Crystal Lye Drain Opener"?

I think this is just like washing soda. I think it could be added to the washer. Thanks for the reply, I think I posted this in the wrong place, as I am still learning this site system.

I also use Roebic NaOH Lye (Crystal Drain Opener) pictured above by Artemis when I am traveling and did not bring enough of what I purchase cheaper online. Before finding an online source that I like (which is often Essential Depot, but I have used others as well), I found the Roebic at Tractor Supply Company. Where I live, and in most states where I have looked for it, I can always find it in a TSC, but it is not always available at many hardware stores, including Lowes or Home Depot. TSC has been the most consistent source for me when traveling.

I agree with Susie, that the Roebic drain opener lye is far more expensive than ED, even with shipping costs included. But for a beginning hobbiest, or someone who doesn't want to wait for a shipment, the 100% sodium hydroxide lye crystals in a drain opener works just fine.

It's not cheaper at Ed, it's 23$ with a 30% off coupon for 4lbs but I just got 4, 1lb Crystal lye drain opener bottles from Walmart for 22$ and I don't have to pay shipping.

HI @Amberlei83 - Earlene's post that you quoted was written in 2017, and prices have fluctuated greatly since then.

Also, if you have Amazon Prime, you can buy the ED lye without paying shipping charges. And if you can buy in quantity from a chemical supplier, it's much cheaper per lb. Of course, not everyone wants and can store 50lb of NaOH around their house.
