We made it down to Jon-Don in Seattle for the IICRC Carpet Cleaning Technician course. 2 full days at Jon Don learning the science of cleaning. I learned many things, including that no matter how long you've been cleaning there is always something you can gain from continuing education. That's Frans and Gavin in the back row at the tail end of the second day listening to a final review before the exam. Thanks Jon-Don for being an excellent host, and Pat Muller for being an extremely effective and knowledgeable instructor.
