## Long description

UN PÅYN DO SPRYSKIWACZY 5L LETNI - NANOTECHNOLOGY is a concentrated 5-litre summer windshield washer fluid formulated for use in warm weather. Designed by UN for passenger cars and light vehicles, the formula uses nanotechnology to help dissolve and remove insects, road film and light dirt from glass surfaces and wipers. Supplied as a concentrate, the product is intended to be diluted according to temperature and local recommendations before filling the washer reservoir.
Advantages
The nanotechnology-enhanced concentrate improves wetting and spreading on the glass, aiding removal of insect residues and thin road grime without streaking when used as directed. As a summer formula, the fluid resists foaming and is formulated for compatibility with common washer systems and rubber wiper blades. Concentrated packaging reduces transport volume and allows adjustment of dilution ratios for local conditions.
Suitable for
 Passenger cars and light commercial vehicles
 Removing insects and fresh organic residues from windshields in warm weather
 Routine daytime cleaning of glass and wiper blades
 Users who prefer concentrated fluids to adjust dilution
When it may not be suitable
This summer washer fluid is not formulated for freezing conditions and should not be used where temperatures drop below the product's intended operating range. It is intended for removing light dirt and insect deposits; it may be less effective on heavy oil deposits, thick road salt residues or industrial grime without pre-cleaning or a stronger detergent.
Key specifications
 Volume: 5 litres concentrated liquid
 Intended season: summer / warm weather use
 Primary function: windshield cleaning; insect and light road grime removal
 Formulation: nanotechnology-enhanced concentrate for dilution
 Compatibility: suitable for standard automotive washer systems and rubber wiper blades
How to use
Dilute the concentrate according to the label instructions or local recommendations for summer use, then pour the prepared solution into the vehicle's windshield washer reservoir. Operate the washer and wipers to confirm cleaning performance and check for any streaking; adjust dilution slightly if needed. Do not mix with anti-freeze washer fluids intended for winter use unless the label explicitly allows it. Store the product in a cool, dry place away from direct sunlight and follow local disposal rules for containers.
What to consider before purchase
 Intended season: designed for summer/warm weather; not suitable for freezing temperatures
 Dilution: product is concentrated—verify recommended dilution ratios for your conditions
 Vehicle compatibility: suitable for passenger cars and light vehicles with standard washer systems
 Cleaning needs: optimized for insects and light grime, not heavy oil or industrial deposits
Usage recommendations
Use the product as a diluted summer washer fluid and refill the reservoir only with the prepared solution. For best results, clean heavily soiled glass separately before relying on the washer system and replace worn wiper blades to maximize contact and avoid streaks.
