TO SOFTEN PUTTY AND REMOVE OLD PAINT.
1. Take three pounds of quickstone lime; slake the lime in water, then add one pound of American pearlash; apply this to both sides of the glass and let it remain for twelve hours, when the putty will be softened, and the glass may be taken out without being broken. To destroy paint, apply it to the whole body which is required to be cleaned; use an old brush, as it will spoil a new one; let it remain about twelve or fourteen hours, and then the paint may be easily scraped off.
2. To remove paint from old doors, etc., and to soften putty in window frames, so that the glass may be taken out without breakage or cutting, take one pound of pearlash and three pounds of quicklime, slake the lime in water and then add the pearlash, and make the whole about the consistency of paint. Apply to both sides of the glass and let it remain for twelve hours, when the putty will be so softened that the glass may be taken out of the frame without being cut, and with the greatest facility. To destroy paint, lay the above over the whole body of the work which is required to be cleaned, using an old brush, as it will spoil a new one. Let it remain for twelve or fourteen hours, when the paint can be easily scraped off.
3. Paint stains on glass.—American potash, 3 parts; unslaked lime, 1. Lay this on with a stick, letting it remain for some time, and it will remove either tar or paint.
