What are the harms of rain repellent to glass?

[MariaAnn]

Rain repellent does not harm glass. Here is relevant information about rain repellent: Function: Rain repellent forms a nanofilm on the glass, which has hydrophobic properties and effectively prevents the formation of a water film that can blur vision. Generally, it has no side effects. Performance guarantee: It not only provides 100% anti-fog effect on car glass but also prevents aging and oxidation. Environmental performance: The material used is an eco-friendly product, non-toxic, odorless, non-corrosive, and highly concentrated, requiring only 2 milliliters per square meter. Cleaning performance: It can clean stains on the glass surface, making the glass more transparent and brighter.
