    Abstract: An improved method of removing rust stains from carpet and other textiles including application of ammonium bifluoride or other fluoride compounds to a rust stain. If the ammonium bifluoride is unable to remove the stain, an acidifying agent is added to the ammonium bifluoride to generate hydrofluoric acid on the stain. The unreacted hydrofluoric acid is then neutralized and removed along with the stain.

  • Patent number: 6099589
    Abstract: In fabric laundry procedures, commercial and household laundry detergent compositions commonly contain an optical brightener composition. Brighteners adjust the optical properties of the fabric in such a way that the fabric appears to be white even after repeated washings. Often white fabrics can yellow during use. Fluorescent optical brighteners having an optical blue aspect, mask the yellowing of the fabric. Common laundry detergents fail to have sufficient brightening capacity to brighten heavily soiled white cotton items used in household, commercial, institutional or fast-food food surface. A process for improving the whiteness of soiled white cotton, preferably terry cloth, items involves contacting the soiled white fabric item with a presoak containing an effective proportion of a fluorescent optical brightener composition, removing the item from the presoak and separating the presoak composition from the fabric item producing an extracted item.

  • Patent number: 6087317
    Abstract: By using a nonionic surfactant as the primary emulsifier having an hydrophilic-lipophilic balance (HLB) greater than about 13, at a concentration sufficient to provide about 0.5-3 molecules per 100 square .ANG. of surface area of silicone particles; and a nonionic cosurfactant having an HLB less than about 11, at a concentration sufficient to provide 5-15 molecules of emulsifier per 100 square .ANG. of surface area of silicone particles; aqueous emulsions containing low molecular weight silicones can be prepared which possess improved particle size stability. In particular, the low molecular weight silicones have a molecular weight less than about 1,000, and a viscosity of not greater than about 5 mm.sup.2 /sec. These emulsions can be used in applications relating to laundry pre-spotting, automotive bug and tar removal, and hard surface cleaning.
