Composición de limpieza de superficie exterior
Una composición de limpieza de superficies externas que comprende: hipoclorito de sodio del 1% al 5,5% en peso; silicato de potasio 0,3% en peso a 3,0% en peso; hidróxido alcalino 0,01% en peso a 0,5% en peso; un agente espumante; ingredientes adicionales opcionales; y balance de agua al 100% (Traducción automática con Google Translate, sin valor legal)
A composition for cleaning external surfaces which comprises an aqueous solution containing 1.0-10% wt alkali hypochlorite and an additive solution containing 0.3-3.0% wt alkali silicate, 1.0-10% wt alkali hydroxide, a foaming agent and water balance to 100%. Preferred compounds are (i) sodium hypochlorite, (ii) potassium hydroxide at a range of 2-8% wt, more preferably 2-6% wt, even more preferably 2.5-5% wt and (iii) potassium silicate at a range of 0.5-2% wt, more preferably 0.3-1% wt, even more preferably 0.5-1% wt. The foaming agent may be a foam stabiliser, preferably an alkyl (e.g. lauryl) dimethyl amine oxide at a range of 1-4% wt, more preferably 1.5-3.5% wt, even more preferably 2-3.5% wt. A method of cleaning an external surface by applying a composition as described above to the surface, letting it remain in contact therewith for a while and then rinsing it with water is also claimed. The composition is suitable for cleaning masonry or other external surfaces such as stonework, bricks, tiles, slates, concrete, composites, cementitious coatings, rendering, woodwork and metalwork, particularly for removing moss, lichen or algae therefrom.
