For my saddle, I use Oakwood liquid saddle soap on it usually once every other week, and condition it with the big can of yellow Passier stuff, not sure what it's called, but it works miracles. I condition it about 2x a week because it scratches really easily and this stuff seems to help prevent it a little.
For my bridles, girth, and tall boots, I use Leather Wash (the spray on stuff in the white & green bottle) which is awesome, then I use Bick 4 leather conditioner which makes everything look wonderful.
Wipe off after each ride, slightly moist sponge, glycerine bar
Good scrubbing/cleanse once a month or prior to a show
Condition- as neccessary
Oil- A couple times per year, depending on need.
What about you all?
Saddle, bridle, boots, whatever other leather products you have.
Same as you for the saddle. However, I don't use conditioner. I consider the pure Neatsfoot oil a conditioner.
Bridle - wipe off with glycerin and warm water after every ride. Hardly ever oil it.
Boots - I only wear them to show, so they don't need a lot of care. If they're muddy when I get home I wash them and let them sit until I polish them for the next show. I use Melatonian (sp?) and a biffing brush. That's it.
