Men who apply two drops of Windex to their penis before going to bed may cause inflammation, allergies and other symptoms in the penis due to the irritation of Windex. Windex is a drug often applied to headaches caused by colds and flu, and is also commonly used for itching caused by mosquito bites. Its main effects are anti-inflammatory, anti-itching, analgesic and so on. The skin of the penis is sensitive and fragile, and applying it to the penis can cause inflammation and allergy due to strong stimulation. Scratching by the patient may even cause ulceration and pus in the affected area, which, in serious cases, may lead to irreversible damage to the male reproductive system, therefore, it is not recommended to apply Windex to the penis of men.
