A. A lot of times in cleanliness and hygiene is not maintained sometimes due to yeast infection also the ageing can be continuous the best you can do right now is to take some warm water if you are willing to add some mild antiseptic liquid do that clean it properly or if you want you can use the soap also to clean properly wipe it out after that apply Boroline antiseptic cream or coconut oil this will be healthy and consult the doctor if needed
