I bought this product a couple of years back to try it and ended up returning it. As far as I'm concerned, it's nothing special to say the least, didn't clean my toilet at all, was about as effective as using water and dish soap. Want to clean your toilet?? Do it the way they did it in the early 1900's. Some Ajax and a toilet brush and maybe a little bleach. My grandmother always had a clean toilet and there were no "special" products to clean with then.
This question would be best answered by the corporate office. I don't know where you live, but I currently buy this product at my local grocery store in Hopkins MN.
No, it is a blue liquid.
I purchased this product about three years ago and the only thing that I remember, IT DIDN'T WORK! I took it back for a refund.
I would try a small area and see how it does.
Always take the time to look up a product's website. If you had, you would have found that they have an "800" number, that might be helpful. I personally don't like the product. Tried it, returned it, it didn't work as advertised.
No, the product will not damage drains or a septic tank.
