Grooming 2
Body brush and metal or plastic curry comb
The body brush is an all over brush that can be used everywhere on the horse - it is the only brush that should be used on the mane and tail. It is good to remove the dust and grit that can be hard to get off with either the rubber curry comb or dandy brush.

If you keep a horse fully stabled, this is probably the only brush that you will need. For a grass kept horse, it is great to just get the dust off in the summer months. Do be careful that you don't use the body brush too much on a grass kept horse as it can remove the oils from the coat that are need to waterproof it.

The curry comb is used to clean the body brush (by pulling one against the other) and should NEVER be used on the horse.
Face brush
The face brush is like a nail brush sized version of a body brush and is used like a body brush on the face.

Stable rubber
A stable rubber is a cloth (like an old tea towel) that is used after the body brush to give the coat a final wipe to ensure that all the dust is removed. It is usually only used at shows as regular use can remove oils from the coat.
Mane comb
The mane comb is used to get the knots out of the mane and tail of the horse. It should not be used on a daily basis as this can easily pull out the hairs leaving the horse with a very spindly looking tail and thin mane.
Summary
In general, start the grooming with the rubber curry comb or dandy brush, then follow up with the body brush. If the horse is basically clean when you start to groom it, a brushing with the body brush should suffice.
Next - picking out the hooves.
