Review: Great Product - Very nice product and worked as advertised.
Review: Works great, a few words of caution below - This stuff is great! We have enough iron in our water that it turns my hair orange in the shower (my hair is blondish). It stains the shower yellow and we get that nasty sulfur smell coming out of the pipes when the washer runs (from iron-fixing bacteria - bacteria that uses iron as an energy source and excretes sulfurous compounds - that's right, that smell if bacterial farts). The tubes coming out of the water softener containing water that should be treated and have little to no insoluble iron were stained yellow. That disappeared and became clear after the softener cycled a couple times with this stuff mixed in. The sulfur smell of microscopic toots vanished. I didn't notice any new staining. I didn't seem to need to use as much as it instructs to (especially for washing dishes/laundry in our second place which has no water softener). I quartered to halved the amount recommended for dishes/laundry. As others have mentioned, you do NOT want to breathe the dust that comes from pouring it. It's really bad (even with a dust mask on). I'm going to try putting it into a container where I can scoop it out instead of pour, so there's less dust. Also, its REACTIVE, so be careful. The instructions say to mix it with cold water (and don't warn about the reactivity) to pour into the water softener. Even though I used bottled water (thinking it wouldn't react to that), It turned into a bit of a volcano and overflowed my container. The overflow was partially dissolved crystals which stained my wood finish. So if you are mixing it, use a large container or a pail on a surface that won't stain (it was fine on granite and in the sink).

## Questions & Answers

**Q: Shall i use rust out in my brine tank when i have a separate green sand iron filter?**
A: The rust created on internal parts of your resin bed is the primary reason to use this product.  In order for the softner to work properly that resin bed needs to be clean of rust and iron.

**Q: What size of 1 pack of Iron Out posted on Amazon**
A: Thank you for your question. Not sure what pack your referring to, but the Iron Out sizes are 4, 22, 76 ounce containers. The 4 ounce is sold in a pack.

**Q: Is this product safe for septic system?**
A: Yes

**Q: Will this clean the white residue in my sinks and on bathroom fixtures? If so, how do I use it?**
A: If the white residue us scale, this might clean it. Rustoff is a dry acid type material, very harsh. I would buy the less harsh scale and lime cleaner.
