Koch Chemie Rapid Rinseless Wash Rrw is the second 'rinseless' that the brand has produced. Instead of being ready to use (RTU), this version comes with a 1:256 dilution ratio, matching the industry standards that the USA has grown accustomed to.
First, development began as soon as Wash & Finish hit the market. This previous version got the cleaning aspect correct, but effectiveness is judged both on cleaning power and cost per application. Massive progress has been made with this version, and Koch Chemie has produced a top tier contender and at minimum matches any similar product on the market; dilution ratio, cleaning power, water conservation.
As mentioned with other rinseless products I offer, I view this cleaning method as a compromise that is situationally acceptable. It is very important to have a method established when using, always working from least to most dirty areas unless being used to clean a vehicle that is already mostly clean. The transfer of dirt from an effected area over to a clean area is a recipe for creating surface issues, and if we're being honest with what surfaces tell us, you need to be on your A GAME with this cleaning method. That said, you cannot deny the use of any rinseless... and this is why I offer it!
Spray bottle and bucket ratios are the same. Use a spray bottle to saturate and encapsulate dirt on an area, allow it to dwell for a moment before 'washing' the area down with a bucket of rinseless solution and a proper wash pad. Once washed with a mitt/pad working top to bottom, wipe that panel down with a dry towel.
My recommendations for additional products to use with ANY rinseless wash:
