I like to take this opportunity and share some information regarding the usage of Dish-washing Soap- the usage of Dish washing soap within the detail industry seems to be accepted/endorsed and promote by many people including top notch professional detailers, at the same time for some reason it appears that is a dead debate and no end on site to it;
Is almost like if you don’t use it you don’t know anything about detailing, at least that is the general impression that some of us perceive.
First; lets analyze why is this product used by so many people within the automobile detailing industry, the “Main” objective to used dish detergent to remove any old waxes or sealants" prior to a new application of waxes/sealants.
From our research we have found two easy ways to obtain such results (but there’s other alternative as well not to mention car care products made especially for this task)
1- Via a oxidation block or Via Clay bar
2- Isotropy Alcohol (rubbing alcohol) a 50/50 mix of water and isopropyl alcohol
This procedure must be done by an experienced person.
Those are just two examples, as we continue we can mention that dish washing detergents are designed to strip grease and grime. In the automobile world it seems that the brand “Dawn” is the one particular brand that everyone referees too, maybe that particular brand of dish washing soap is stronger or is just the branding, I suspect the second one.
With that we will concentrate on that brand.
We can write pages on this subject, what we post are things based on our experience but to make it fair, why don’t we ask the product manufacture? I'm not into the dish washing soap business so it only makes sense to ask them. So we did some research and our finding were;

Question
Can I wash my car with dish washing detergent?
Answer
your car surface and the dirt that gets on it are a lot different from the food soils and dishes that dish washing liquids clean effectively. We don't recommend them for cleaning your car.
"Can I use Dawn to clean things other than dishes?
Dawn is so effective in cutting grease on dishes that over the years, consumers have used Dawn on other greasy messes around their homes, from cleaning kitchen messes like grease build up on the stove range hood to oily spots in the garage. Dawn is not recommended for window cleaning, car washing, body wash or washing hair.
This is coming from the product manufacture not from Me, just in case here is the source directly from them.

So the main question reminds, WHY go against the product manufacture recommendations?
I hope some of you will find this information useful.
