Nice fresh and clean.
Scent: Lemon
I use this for general cleaning, smells fresh, and picks up dirt. I also like it for my acrylic bath tub to remove soap build up no scratching.

When you need some real cleaning power.
Scent: Lemon
Be careful of this stuff. It is very powerful. But wow, does it clean. It can cool rust off of many items. Smell is overpowering. Price is terrible but what else is new? It does not foam unless it comes into contact with something reactive. I put mine in a squeeze bottle for better application.
