After the hours of riding in dusty arenas and long trail rides, dirt gets imprinted in every crease of the saddle. But there is nothing a little work can’t get out.
Soak a sponge in a bucket of warm water.
Wring out the sponge till damp and wipe your saddle and tack(this opens the pores of the leather in the saddle to thoroughly clean and condition your tack when saddle/leather soap is applied.)
Work in the soap into the leather from top to bottom,underneath and everywhere in-between.This may take some elbow grease and you might get a sore hand but the finished result is a nice supple saddle fit for a show.
Use a dry rag to wipe ALL the suds off the saddle.
Since you’re already covered in suds and want your saddle to look brand new, why not shine it up a bit. A saddle shine and conditioner will make the leather supple, and look like it did when you bought it.
You can usually wipe all non-leather parts of a saddle with a damp cloth, or sometimes use a carpet cleaner.
