If a black, blue, or brown coat, dry 2 ounces of Fuller’s earth, and
pour on it sufficient boiling water to dissolve it, and plaster with
it the spots of grease; take a pennyworth of bullock’s gall, mix with
it half a pint of stale urine; and a little boiling water; with a
hard brush, dipped in this liquor, brush spotted places. Then dip the
coat in a bucket of cold spring water. When nearly dry, lay the nap
right, and pass a drop of oil of olives over the brush to finish it.
If grey, drab, fawns, or maroons, cut yellow soap into thin slices,
and pour water upon it to moisten it. Rub the greasy and dirty spots
of the coat. Let it dry a little, and then brush it with warm water,
repeating, if necessary, as at first, and use water a little hotter;
rinse several times, in warm water, and finish as before.
