Abstract: Water-dilutable screen cleaning concentrate (A), with nano-components with freeze protection to -30[deg]C, comprises: monovalent alcohol (30-40 wt.%); polyvalent alcohol (5.25-8.5 wt.%); surfactants (1.5-3 wt.%); complexing agent (0.15 to 0.85 wt.%); particle (nano-components) (0.2-1 wt.%); optional components (up to 1 wt.%) e.g. aroma material; and water (added to make up to 100 wt.%). Water-dilutable screen cleaning concentrate (A), with nano-components with freeze protection to -30[deg]C, comprises: at least a monovalent alcohol (a) (30-40 wt.%) such as 1-4C alkanol; polyvalent alcohol (b) (5.25-8.5 wt.%); surfactants (c) (1.5-3 wt.%); complexing agent (d) (0.15 to 0.85 wt.%); particle (e) (nano-components with a particle size of 5-500 Nm) (0.2-1 wt.%) that modifies the surface optionally by complexing agent (precipitation of silicic acids, aerogel, xerogel, magnesium hydroxide, boehmite, aluminum oxyhydroxide, zirconium oxide, zinc oxide; cerium oxide, ferric oxide, magnetite, titanium oxide, titanium nitride, hydroxyl apatite, bentonite, hectorite, silicon dioxide-cerium dioxide, stannic oxide, indium oxide-stannic oxide, magnesium aluminate, hafnium oxide such as silicon dioxide-brines, aluminum oxide-brines and/or titanium dioxide-brines) (preferably coated silicon oil); optional components (f) (up to 1 wt.%) such as aroma material, dye, pH controlling agent, enzyme and rectifiers for detergent and cleaner; and water (g) (added to make up to 100 wt.%). Independent claims are also included for: (1) a water-dilutable screen cleaning concentrate (B) (as a year screen washer) with nano-components and freeze protection, comprising (a) (0.25-1.5 wt.%), (b) (preferably propylene glycol) (8-12 wt.%), (c) (45-55 wt.%), (d) (0-1 (preferably 0.1-1) wt.%), (e) (0.2-1 wt.%), (f) from preservative, dye, perfume oil and usual additives for cleaner (1 wt.%) and (g); (2) a two-phase cleaning system, for cleaning vehicle screen and headlights, comprising: at least a liquid, (A) for pre-purifying the contaminated windowpane and for smoothing the glass surface; and optionally diluted cleaning concentrate or (B); (3) a winter screen cleaner liquid (obtainable through diluting (A) (0.5-100 parts by volume of water)); and (4) a winter screen cleaner, with freeze protection up to -20[deg]C, with nano-components comprising: ethanol (25-30 wt.%), propylene glycol (1.5-2.5 wt.%), nitrilotriacetic acid (0.15-0.75 wt.%), propanetriol (3-4.5 wt.%), coated silicon oil (0.2-1 wt.%), dye (0.005-0.01 wt.%), citric acid (0.01-0.3 wt.%) and (g); and (5) a liquid, water-dilutable glass cleaning concentrate with nano-components, comprising: aliphatic hydrocarbons (5-12 wt.%) as solvents, emulsifying agents (1.5-2.5 wt.%), (b) (preferably glycolether of ethyl glycol, propylene glycol or glycerin) (1.5-2.5 wt.%), (a) (1.5-2.5 wt.%) such as isopropanol, (e) (with a particle size of 5-250 Nm) (5-15 wt.%), (c) (0.04-0.1 wt.%), controlling agent (particularly natural thickeners or surfactant thickeners) (0.5-2 wt.%), preservative (0-0.3 (preferably 0.1-0.3) wt.% and (g).
