I am not affiliated with this company but I am so pleased with how it works I thought I would post information for anyone else who might be interested.

If anyone else has tried it, I'd be intersted to hear what you think. Wondering if there are any uses for it I haven't thought of yet.

I purchased an 800 g container more than a year ago and went out to get a new one today. Lasts a long time and I would almost call it a "miracle cleaner".

I have stainless appliances and this removes all the water/drip marks and makes the steel look new. It also cleans my black granite counters beautifully. No water marks. I use it in the kitchen and bathroom with great results.

It polishes my polished nickel kitchen faucet as well. Removes the tarnish marks. I have used it to polish silver pieces as well.

While I was getting a new container today I met a lady buying several. She runs a local cleaning company and said she uses it as their primary cleaner. She said her clients love it.

I took the following from their website:
