Wash it out really good and cover it with a gauze pad. Change the gauze pad either tonight or tomorrow. You will be fine.
If you can get to pharmacy (call first to see if they have it) get ‘Butesin Picrate’. It’s great on burns.
As previously told, clean, dry and put triple antibiotic ointment on thinly, cover. Change daily and keep using ointment.
You;ll be fine.
