Hi everyone,
I also clean my boots after each trip with a stiff bristle brush and a solution of clorox and water. I usually then leave them in the sun to dry. I think the clorox scrub is a good idea just in case there are any WD bacteria I may have picked upon them. All gear gets a cleaning too. If my excursion is for more than one day, I will wait until the end of the trip. I still have one pair of boots that are 12 years old and are in excellent shape except that the studs are rusting somewhat but still very serviceable.
