Folks I have purchased APC/Degreaser from company called Wavex and they suggest for use in various dilutions for strong and lesser surface decontamination from grease and oils. Also it can be used on various types of materials with out issues. I was able to thoroughly clean up my engine bay, wheel well and car tires with this after recent rains in the city. Have observed it has good sud formation in higher concentration and works well to remove road grime from running board. It has a very pleasant perfume to it. I am diluting it 10 ml to one liter water in a spray can and directly spray to required area and agitate with brush. Can be directly ordered from their online store.
