Do I need to use a special curtain cleaner to clean the window PE sunshade?

Cleaning window PE sunshades usually does not require the purchase of so-called "curtain specific cleaning agents". The following are specific analysis and suggestions:

1. Special cleaning agents are not necessary and carry risks
Most of them belong to marketing concepts: Some "curtain specific cleaning agents" on the market have unknown ingredients and may contain strong solvents or alkaline substances, which can corrode PE materials and cause them to become brittle and white.
Uncontrollable ingredients: If not clearly labeled as "suitable for PE/polyethylene materials", blind use may permanently damage the curtain surface.

2. Clear water is the first choice, gentle and effective
Basic cleaning is sufficient: Dust and ordinary stains can be removed by rinsing with room temperature water and gently wiping with a soft cloth without damaging the material.
Key action: Be sure to remove the curtain and rinse it thoroughly before drying to avoid residue of scale.

3. Stubborn stains can be replaced by household neutral cleaners
Safe choice: A small amount of daily neutral cleaning agent is sufficient, such as: #  Dishwashing liquid (such as dishwashing detergent) #  Hand sanitizer/shower gel
Key point: It must be neutral (pH ≈ 7) and free of bleach/strong acid and alkali components.
Usage: → add 1-2 drops of detergent to 1 liter of clear water, stir it evenly to form thin foam water → dip it with a soft cloth, gently pat the stain (do not rub it hard) → thoroughly clean the residue with clear water within 3 minutes

4. Absolutely avoided types of cleaning agents
*  Strong alkalinity: Kitchen oil stain cleaner, soap powder
*  Strong acidity: ceramic tile cleaner, descaling agent
*  Containing solvents: disinfectant with an alcohol concentration greater than 70%, and adhesive remover
*  Containing abrasive particles: cleaning paste, baking soda paste

5. Alternative solutions are more practical than specialized agents
Slight yellowing/odor: Gently wipe with white vinegar and water (ratio 1:15) and rinse immediately (vinegar odor disappears as soon as it evaporates).
Dust maintenance: electrostatic precipitator/ultra-fine fiber cloth dry wipe, safer than using chemicals.
