Audi RS5 with milk spilled under the passenger seat. James extracts the liquid from the soaked foam, dries overnight, and removes the smell. Exterior tar removal, detail, polish, and coating followed.
Milk had spilled in this Audi RS5 -- enough to soak under the passenger seat and into the foam underneath the carpet. The problem with milk is not the liquid itself but what happens as it breaks down: the smell works its way into the foam cells and does not come back out easily.
The passenger seat came out and the trims were pulled. James shampooed the surfaces and decontaminated the runners and plastics before going underneath the carpet to find the foam. The foam had visible discolouration where the milk had penetrated, and the smell coming off it was strong. He had to extract the liquid from the foam before the drying machine could do anything useful -- if you dry saturated foam without extracting first, you are just concentrating the smell as the moisture evaporates.
Drying machine in overnight. The next morning the foam was dry and the discolouration was still there, but the smell was gone. Box sections cleaned and decontaminated. Everything reassembled. The mats were still drying at that point.
With the interior clean, the work moved outside: tar removed from the bodywork, full detail, machine buff, coating applied. The car left looking as good outside as it smelled inside.
