If the heart of the reflective back is damaged, of course it needs to be cleaned. For what method to use, we can consult the manufacturer of the reflective vest.
Before we clean the reflective vest, we must first choose a suitable detergent. Note that reflective materials can only be wiped with cleaning agents. Do not use corrosive substances, such as disinfectant powder. When cleaning, please remember not to use alkaline detergents such as washing powder, soap, and neutral detergent. If it is difficult to judge the nature of the solution, you can use bath lotion or shampoo instead. When washing, dissolve the neutral detergent in cold water, and soak the dry reflective vest for 20-30 minutes.
Then gently rub it with your hands. The areas with heavy stains on the collar and cuffs can be pretreated with a solution such as Collar Cleaner first, and then lightly brushed with a soft brush after soaking. After washing, do not use a spin dryer to dehydrate, hang in a cool place to dry.
