Application of Solvents
There are four ways to apply a solvent to a fabric for removing stains:
- application of pressure
- front sponging
- This is the most common way of treating non-washable fabrics. The front of the fabric is sponged with a sponge that is soaked in the solvent being used. The rear of the fabric should be backed up with a clean, absorbent, material. The stain is rubbed with the sponge radially, from the centre of the stain towards its edge. It is important not to rub the sponge in a circular motion, as that causes the stain to spread in rings.
- back sponging
- The stained side of the material is placed face down on a clean, absorbent, material. The back of the fabric is then sponged with a sponge that is soaked in the solvent being used. It is important not to rub the material with the sponge, but to use a padding motion, so as not to spread the stain. The solvent dissolves the stain, which is deposited on the absorbent material beneath. To completely remove the stain it may be necessary to use more than one absorbent pad.
Famous quotes containing the words application of and/or application:
“I think that a young state, like a young virgin, should modestly stay at home, and wait the application of suitors for an alliance with her; and not run about offering her amity to all the world; and hazarding their refusal.... Our virgin is a jolly one; and tho at present not very rich, will in time be a great fortune, and where she has a favorable predisposition, it seems to me well worth cultivating.”
—Benjamin Franklin (17061790)
“If you would be a favourite of your king, address yourself to his weaknesses. An application to his reason will seldom prove very successful.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (16941773)
