Bought the 500mL size to try out, used it for the first time over the weekend and really enjoyed it. Diluted 1:5 in a pump sprayer and used as a pre-rinse for a mildly filthy car and I was very satisfied with the outcome. Applied to a dry car then rinsed with water and except for some crevices the majority of the grime was lifted. I also really enjoyed the smell of this one, nothing harsh on the nose and I do like the fact that it's biodegradable. For the moment, I plan to continue using this as a pre-rinse, but I will alter the dilutions based on how dirty the cars are.

Best Apc for Pre-Rinse and wheels and tires. i personally dilute it 1:1 for wheels and tires and 1:4 for a pre-rinse.

Cleans okay but I want impressive or anything

This is a superb cleaner. I used it today for the first time on my engine compartment and it did a great job. It is better than the "Super Cleaner" I have been using. The spray nozzle fits my hand perfectly and is probably one of the better ones on products I buy.

So far so good! As I write this I am pleased but still testing. Right now @ 1:25 ratio it has done everything I use an APC for. My first smile using it was it melted a Tar/Grease booger off rocker panel on the wifes Mercedes.

My new go to apc! It accomplished what another big name brand couldn't.
