Suggest Remedy For Second Degree Burn With Fluid Discharge

Yes thank you, i have a 2nd degree burn on my calf from falling asleep on a heating paid one night. I've been nurseing it now for 3 weeks it is starting to look alittle better but there is still fluid uzing out of it and it's a bit disturbing to me. I have cleaned it every 2 days with alcohol, peroxide, & neosporin then cover with a dressing. It looks gross to me so i need to know what to do from here. Any advise would be helpfull
