The 3D orange degreaser is fantastic and uses d-limonene which is an organic citrus solvent. Orange Degreaser smells great and can be used as an interior cleaner when diluted 10:1 or even 15:1. For cleaning wheels, tires, and wheel wells it's great at 4:1 or even 10:1. I think Orange Degreaser is the best performing VALUE based degreaser/apc on the market.
What makes 3D orange degreaser better than Meguiar's Super Degreaser IMO is that 3D it isn't a "hot" butyl degreaser which will make you cough when you breath it in and can cause internal burns and bleeding. Also, even without these "hot" chemicals, 3D orange degreaser is better at removing tire browning and the slimy tire dressing build up we all encounter from time to time. 3D is also really dedicated to manufacturing eco-friendly, biodegradable chemicals that are all VOC compliant and meet even California's strict environmental regulations.
I haven't tried 3D yellow degreaser yet, but i've heard great things about it. But, unless you are buying a degreaser to use primarily on wheels and tires then I personally would recommend buying the 3D Orange Degreaser.
