Yeah...I picked up on this also several weeks ago and bought some LA Totally Awesome.... great stuff for motorhomes and trailers[white]. i used a soft brush on a stick and used it 50/50. What worked well was and old Windex Outdoor bottle with the built in nozzle[off...rinse...clean] at 50/50. Squirt it on brush it around....rinse. Tough to find some stuff that impresses these days.
