Anyone use soda ash instead of Arm & Hammer Super Washing Soda?

I can't seem to find a store local that sells Arm & Hammer Super Washing Soda. But we have plenty of pool and spa store that carry soda ash.

All I have ever seen mentioned on the forum is the A&H product. Am I the only unlucky soul that has to go to the pool store to get some? :chuckle:

Pool supply pH+ consisting of sodium carbonate (aka soda ash) will work fine.

I must have glossed over that part when I was reading that. Thanks for pointing it out!

Pretty sure I have seen both at Wal-Mart.
