Let me start by saying that do not let the price scare you away. This is absolutely the best cleanser I have ever bought and believe it or not, I bought it from a door to door sales person.
The Wonder Cleaner has a citrus scent, so it is not nasty smelling at all. It is super concentrated, so I usually put 1 part cleaner to 20 parts water. This is a multi purpose cleaner that is non-toxic and biodegradable.
I used this on everything, to clean the bathroom, kitchen, spots on the carpet, as a pre-treatment for spots on clothes. When the salesperson was demonstrating, you can make it more concentrated and use it to remove oil off of your driveway.
This cleaner is absolutely wonderful. I just finished the bottle I had and that was the second bottle I had purchased in 5 years, yes I said 5 years.
