There are very many methods to do this.
- You can use a cut lemon. Rub the cut surface on the slime under a running tap. Not for too long though as the acid will start to peel off the skin.
- You can use garri. The abrasive texture of the garri granules on the skin of the catfish will get rid of the slime
- Hot Water – not my favorite method because it starts to cook the catfish before it gets to the pot
- Ash – also not my favourite due to concerns about contamination
