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; First; lets analyze why is this product used by so many people within the automobile detailing industry, the “Main” objective to used dish detergent is to remove any old waxes or sealants" prior to a new application of waxes/sealants. With that we must learn that there’s a difference between Wax and Polish Wax: A true wax contains carnauba, bees wax, or paraffin wax. The term wax is used two ways. You can use the word "wax" as a process upon where you apply a protective coating to a surface which could be a polymer or use a product with a wax in it. Polish: A true polish contains an abrasive that will remove scratches or oxidized paint. It also will bring a dull finish to a shine. More aggressive polishes can remove orange peel, deep scratches, and also oxidized paint. Back to the Dish washing Soap procedure - as mentioned before it is “Intended” to remove all of the above mentioned earlier in aims to prepare the surface. From our research we have found other 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 oxidation block or Via Clay bar 2- Isopropyl Alcohol (rubbing alcohol) a 50/50 mix of water and isopropyl alcohol. Those are just two examples, 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. 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. I did some research and my findings were; This is posted on Dawn's site in their customer support section 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. Question and Tips So the main question reminds, WHY go against the product manufacture recommendations? Anyone care to comment I hope some of you will find this information useful.
