Is Dawn Safe for Septic?

Well, I think it is safe for septic.

I was just asking my Realtor about being safe with a septic tank on a property I am trying to buy & she said that products have a come a long long way since that was the case years ago, when things weren't as safe.
I believe it.

Never heard of anyone having problems with Dawn in the septic tanks. I had mine about 10yrs. and my sister has had hers about 18 yrs. we both use Dawn and have not had any problems. Knock on wood.

It has been used in our septic since 1997 with no problem.
