In some situations, this isn't far off from what some keepers have used, just not the right one for your particular snake. Had this been a bioactive setup for a smaller species, this wouldn't be a bad start to mix in with other elements like some bark chips and leaf litter.
Bioactives just don't typically work as easy for a ball python because they're heavy bodied and like to smush the plants. They also do have some sizeable waste to break down and would still need regular spot cleanings regardless... so most keepers just keep it clean and use a product that is a bit less likely to promote microbial growth
I'd follow along with Albert's suggestion to use paper towels temporarily to make sure there isn't more irritation and this heals up okay. That area is already one where the skin folds are a bit more visible because of the stretching required for feeding, so any irritation can look much worse than it really is, but it doesn't hurt to be cautious!
