Definitions

  • the present invention relates to a cleaning solution, and more particularly, relates to a novel cleaning solution containing lignin sulfonate as the primary cleaning agent.
  • compositions containing various solvents and detergents function effectively, they can, in the case of solvents, be dangerous to employ and the problem of disposal of the solvent is always present.
  • Detergents have also been widely used; however, they are frequently not as effective as the harsher solvents. Furthermore, biodegradability of detergents is an ever present issue.
  • a method of cleaning a surface comprising the step of applying an aqueous cleaning solution to the surface wherein the active cleaning ingredient of the aqueous cleaning solution consists essentially of a lignosulfonate.
  • Lignosulfonates have been utilized in cleaning solutions in the prior art.
  • a method for the cleaning of a substrate to remove hydrocarbon therefrom comprising the step of applying to the substrate a composition comprising a lignosulfonate and a microbially effective amount of micro organisms.
  • a cleaning composition comprising a liquid multi phase composition with at least two continuous phases and which contains a relatively small proportion of a lignosulfonate.
  • the lignosulfonate is effective, even without the microbial bacteria, to clean different types of surfaces.
  • Lignosulfonates are salts of lignin sulfonic acid which is the reaction product of lignin and sulfurous acid which is obtained in the sulfite pulping of wood to obtain cellulose.
  • lignosulfonates are known including alkaline metal and alkaline earth metal lignosulfonates and the ammonium lignosulfonates, all of which are suitable for the purposes of the present invention.
  • the method of the present invention can be applied to many different types of surfaces.
  • the surface may be either vertical or horizontal or at some other angle.
  • the surface may comprise practically any material as the lignosulfonate is generally not considered to be deleterious to any of the known surfaces.
  • the lignosulfonate can be applied to all types of flooring material (with appropriate caution taken for materials adversely affected by water).
  • the concentration of the lignosulfonate in the aqueous solution may vary depending upon the particular use of the cleaning solution. Generally, a ratio of between 3 ml and 60 ml of lignosulfonate per liter of water is satisfactory with a preferred ratio being between
  • the cleaning solution may, if desired, contain other ingredients with the understanding that the main cleaning ingredient is the lignosulfonate.
  • the cleaning solution may include certain enzymes, surfactants, polymers, etc.
  • the cleaning solution may be used over a wide PH range — i.e. between 2 and 13.
  • the cleaning solution will be applied by appropriate means depending on the surface being treated. Thus, it may be poured, sprayed, or wiped on. Appropriate cleaning implements may be used in conjunction with the above.
  • the cleaning solution may be applied and left for a period of time. Scrubbing implements may be utilized with the remaining solution/debris being appropriately removed.
  • Step 1 General cleaning - Blended 30 ml of dry ammonium lignosulfonate (ALS) in 4.5 litres of hot water in a mop bucket. The mixture was allowed to let stand for about 5 to
  • Step 2 Mopping and degreasing kitchen floors - Blended 45 ml of ALS with 4.5 litres of hot water and was allowed to let stand for at least 90 minutes.
  • Product was sprayed on (60 ml to 4.5 litres ratio) the surfaces multiple times and left for about 10 minutes. Cleaning conducted in the same manner as in step 9 above, using the same dilution and cleaning implements.
  • Housekeeping cleaning is done on a 24-hour basis with guestrooms done during the day, as well as all of the public areas and a first cleaning of the restaurant in the afternoon.
  • the evening houseperson spot cleans public areas and washrooms, including brass cleaning.
  • the overnight cleaner does the second cleaning of the restaurant, the pool and hot tub area, loading dock, all public washrooms, and the lobbies.
  • the hotel has 25 smoking rooms in its 155-room inventory located on the 2 nd floor of the Tower section. Keeping these rooms clean and smelling clean has always been more challenging.
  • a cigar smoker occupied one of the smoking rooms, and the room was saturated with smoke.
  • the room was cleaned with the product, as were the drapes and carpet with a light spray of the product. After inspection, the floor supervisor was consciously surprised to find the aroma of cigar smoke was gone. Nornially, the room would need to be put out of order and aired out for at least a day, along with liberal use of an air freshener.
  • An area that has always been a challenge is the tile floor of the pool area.
  • the product and the rotary machine then tackled another problem area.
  • the tile floor in one of the men's public washrooms is a textured tile, and regular mopping with a chemical cleaner would leave dirt residues in both the grout and nooks and crannies of the tiles.
  • the representatives used a spray bottle of lignosulfonate to lightly wet down about four 12 x 12 tiles.
  • the product lay on the floor for 5 minutes. Within seconds of the brushes scrubbing the tile, the dirt literally flaked off of both the tile and the grout.
  • the field test was to be restricted to the housekeeping area only. However, some kitchen staff heard of the cleaning effectiveness of lignosulfonate and asked to try it. A demonstration of lignosulfonate was arranged, and the product was used to effectively clean grills in the ovens. Subsequently, the kitchen received their own 22.5 litre container of lignosulfonate that was used to clean the floor, the hoods, and the stainless steel tables and equipment. The dishwashing staff even found another use when some lignosulfonate was sprayed into a large pot that had burned food on the bottom. After spraying the pot with lignosulfonate and letting it sit for ten minutes, the burned food residue lifted right off.
  • the dishwashing staff member stated that he just had saved himself a good 30 minutes of scrubbing. Even the line cooks started using lignosulfonate by cleaning a salamander in less than 10 minutes, which normally would take twice that time. The thing that really impressed the kitchen staff was the fact that they did not need to wear masks, respirators, heavy aprons, or acid resistant gloves.

Abstract

La présente invention concerne un procédé de nettoyage de surface, comprenant l'application d'une solution de nettoyage aqueuse sur la surface, l'ingrédient de nettoyage actif de la solution aqueuse étant composé essentiellement d'un lignosulfonate. On a découvert que le lignosulfonate pouvait jouer le rôle d'agent de nettoyage pour divers matériaux de nettoyage.
