Take good care of your equipment. This makes the equipment last longer and be more comfortable for both you and your horse. Make it a habit to wipe all equipment clean after each session, then it won't take you that long.
All leather equipment; saddle, bridle, headcollar, leg boots, riding boots, or shoes should be wiped clean from dirt with a slightly damp sponge and saddle soap. When needed, you should also apply leather conditioner or oil, to protect and condition the leather. It is also good to use a cover for your saddle, to keep it free from dust. All leather is best kept in a place that is dry and not too hot. Never dry damp leather over a heater as this will cause it to dry up and crack.
Conditioner
Contains different oils and waxes. Makes leather soft and gives a slightly water repellent surface. Re-oiling is done after cleaning with soap.
Oil
Protects against water, damp, mould and salt/salt water (sweat). Keeps the leather soft and supple and makes it "resistant to tearing". Contains mineral oils, animal and vegetable fats. Good on leather that has become dry. You should not use too much along the seams as it can easily become airtight and the seams can "rot" and give. This generally applies to all leather oil.
Glycerine soap
Glycerine is also a preservative and softener for leather, and is especially good for light leather. It has a greater polishing effect and is therefore preferable if you want your leather to shine.
Lanolin soap
Lanolin is a preservative and softens leather. Use with very little water.
