Grease-spots from cotton or woollen materials of fast colours, absorbent pastes, purified bullock's-blood, and even common soap, are used, applied to the spot when dry. When the colours are not fast, use fuller's-earth or pulverized potter's-clay, laid in a layer over the spot, and press it with a very hot iron.
For Silks, Moires, and plain or brocaded Satins, begin by pouring over the spot two drops of rectified spirits of wine; cover it over with a linen cloth, and press it with a hot iron, changing the linen instantly. The spot will look tarnished, for a portion of the grease still remains: this will be removed entirely by a little sulphuric ether dropped on the spot, and a very little rubbing. If neatly done, no perceptible mark or circle will remain; nor will the lustre of the richest silk be changed, the union of the two liquids operating with no injurious effects from rubbing.
Essence of Lemon will remove grease, but will make a spot itself in a few days.
