I've used both ONR and DP W&G and they both work great for what they are. In a perfect world everyone would have access to free flowing water, warm temperatures, no restrictions on where they can wash their car ect.
Problem is we don't live in a perfect world and not everyone has access to free flowing water, (you know, a garden hose and a water spigot), or has the ability to use free flowing water due to restrictions.
Here's a list of some reasons for using a Rinseless Wash....
Areas with government enforced water restrictions
In today’s reality, there are many Cities and even entire countries with Government Enforced Water Restrictions. In these places it’s against laws and/or regulations to wash your car with a free flowing source of water.
Geographical areas of drought
In some places there may be no official restrictions against water use but the geographical area itself is experiencing severe drought and self-compliance as well as common sense prevents people from using a free flowing water source to wash their vehicle.
People who live in apartments
In some areas if you live in an apartment, a Condo or a Townhouse, there may be no place to wash your car with a free flowing source of clean water or their may be rules against it that you have agreed to comply with.
Washing in cold winter months
In cold weather, extreme low temperatures can make washing a car with a free flowing water source dangerous and difficult at best.
Mobil Detailers
Rinseless Washing enables mobile detailers to get their customer’s car clean without having to depend upon a water source on location or the extra hassle of transporting hundreds of gallons of water in their Truck, Van or on a Trailer. Besides that some areas require mobile detailers to contain and capture their run-off water and this is an added expense, somewhat difficult as well as time consuming.
Anytime you’re traveling
If you doing any long distance traveling, Rinseless Washing enables you to wash your car while in route.
There are limits as to what you should tackle with a rinseless wash and what you should take to a car wash, below are some examples...
This is light dirt accumulation
This is a good example of a vehicle that can be washed using a rinseless wash.
This is heavy dirt accumulation
This should be taken to a commercial do-it-yourself car wash and have the large chunks sprayed off with a strong blast of water. (Which is what we did after the mud races)
