Definitions

  • the present invention relates to an improved oven cleaner and to a method for removing baked on fats and greases from cooking surfaces.
  • Oven cleaners are compositions of matter used to remove baked on fats and greases from cooking surfaces. Such compositions are commonly used for cleaning ovens as the name implies but may also be used to clean other cooking surfaces on which there has been a build up of baked on fats and greases. Such surfaces include fry pans, kitchenware, barbecue equipment, cooking utensils and the like. These surfaces may be of bare metal, metal coated as with baked enamel, glazed stoneware, porcelain, glass or the like.
  • oven cleaners are based on caustic soda. It has generally been considered necessary to use a caustic alkali in order to effectively saponify the fats in the baked on material in order to enable its removal.
  • a few oven cleaners have been based on solvents, acetate salts, amines or ammonia.
  • the known caustic based systems suffer from the disadvantage of being quite hazardous and/or require the consumer to wear gloves during usage. These known caustic-based systems are required to carry poisons schedule labelling and warning statements.
  • the systems based on acetate salts have the disadvantage that they require temperatures of 250°C or above to activate them.
  • the present invention consists in an oven cleaner containing as active ingredients an effective amount of an alkali metal bicarbonate, sesquicarbonate or carbonate or a mixture thereof and a polyhydric alcohol which is liquid and substantially non-volatile at the desired cleaning temperature and in which the alkali metal salt is soluble at that temperature.
  • the present invention further consists in applying the oven cleaner according to this invention to a cooking surface carrying baked on fats or greases, heating the cooking surface to at least 125°C, and preferably from 125 to 250°C, for a period of at least five minutes and washing and/or wiping the saponified fats or greases from the cooking surface.
  • the oven cleaner according to the present invention may have a pH as low as 9 or less which allows its use without rubber gloves and like protective clothing. These oven cleaners also have the advantage that surfaces of stainless steel, aluminium, and some other metals will be left with a shiny surface after cleaning rather than being left with a dull, oxidised, surface as is the case with many of the prior art oven cleaning compositions.
  • the non-caustic alkali metal salt is most preferably sodium or potassium bicarbonate.
  • Other alkali metal salts which can be advantageously used include sodium or potassium sesquicarbonate, and sodium or potassium carbonate.
  • the alkaline salt preferably comprise from 0.5 to 20% by weight of the product and most preferably 2 to 20% by weight.
  • the pH of the product is preferably below 11 and more preferably below 10 and most preferably 9 or below.
  • the polyhydric alcohol used in the present invention preferably have the general formula:
  • the oven cleaner according to this invention preferably includes water.
  • the water is preferably present in an amount of at least 35% by weight.
  • the oven cleaner is preferably water based and preferably contains a thickener to prevent it running off vertical surfaces.
  • Other ingredients may include a surfactant or soap, a fragrance, a pigment marker and a propellant.
  • the oven cleaner according to this invention may be applied in any suitable manner. These include an aerosol, a trigger or pump spray, a brush or pad.
  • the oven cleaner is preferably applied to a surface to be cleaned and heated to a temperature of from 125°C to 250°C for a time of from 5 minutes to 2 hours.
  • oven cleaners according to this invention are effective, despite their limited alkalinity and the evaporation of the water from the cleaner, due to the continued action of the alkaline salt dissolved in the non-volatile polyhydric alcohol.
  • the alkaline salt is maintained in a condition in which it is available for reaction with the baked on fats and greases at the required elevated temperature by being dissolved in the polyhydric alcohol. For this reason the polyhydric alcohol is required to be substantially non-volatile at the cleaning temperature.
  • Test surfaces were prepared by baking smeared dripping onto white vitreous enamel metal plates for 1 1/2 hours at 250 C. °The baked-on dripping could not be removed at all by washing or wiping without a scourer.
  • Cleaners consisting of the formulations given below were applied to the test surfaces to be cleaned from a trigger pack -after shaking well.
  • test plates were then heated in an oven for 30 minutes to a final temperature of 150°C.
  • test plates were then either rinsed under a fast running tap or wiped with a damp sponge and the percentage removal of baked-on dripping recorded.
  • a cleaner consisting of the following formulation was applied to a test surface to be cleaned, prepared as for Examples 1-9, from an aerosol pack after shaking well. The test was then carried out in the same manner as for Examples 1-9.
  • a cleaner consisting of the following formulation was brushed onto a test surface to be cleaned, prepared as for Examples 1-9. The test was then carried out in the same manner as for Examples 1-9.
  • composition according to Examples for instance, 1 to 5 was equal to that of a molar equivalent active level of caustic soda in the same formulation base.
