Western riders rarely clean their tack and it also lasts for decades.
Lots of aspects of horse care that derive from the British tradition are extremely time consuming. Cleaning all your tack every single day is one. Another are things like grooming and rubbing for let’s say 15 minutes, and another is hot walking forever and ever. Also anything to do with braiding and wrapping legs. Now one of the important things about the British tradition was that up to the early 1900s, it was mainly practiced by wealthy people with grooms, and then over the course of the 20th century that “groom style” standard of horse care got taught as daily care for hands-on owners, through things like Pony Club.
One night I was at the barn alone cleaning tack (which I do from time to time), and enjoying the quiet and listening to the horses eat, and thinking for some reason about the British 19th century (maybe it was first season Downton Abbey). And I thought how of all the servants’ jobs on an estate, being a groom would be one of the best, because it got you out of the house, and away from the eyes of the employers. And then I thought of course, if you were a groom circa 1850 it would absolutely be in your best interest to maximize the amount of time you needed to spend on horse care. Because all the servants worked sunup to way past sundown, and if you regularly breezed through your chores in one sector, I’m sure they’d find you chores in another. So if you were a groom and you loved being around horses, absolutely it would make sense to evolve standards of horse care that kept you happily in the barn, and not peeling potatoes or mowing the lawn or whatever.
So yes, the horses need to be hotwalked an hour a day, and they need to be brushed and “strapped” an hour a day each, and every piece of leather needs to be cleaned and polished every single day.
Now I am currently riding and doing chores for two horses a day at a self board barn, meaning I clean and feed and mix mash, and groom and tack up and untack and etcetera. Plus drive out to buy grain as needed and organize the hay deliveries every couple months and trailer out to for rides off property almost every week in summer. Cleaning the tack every time I ride is not going to happen. And my tack lasts. Leather getting too dry or too wet and moldy is a problem. Leather just getting a bit dirty is not.
I also find the mares I ride don’t love being brushed. Yay for washracks with warm water. They love that!
And another random thought: I seem to recall that at one point English riders didn’t use saddle pads? If that was so, then absolutely you’d need to clean the underside of the saddle after every ride.
