If food residues are stuck to the bottom of the pan, you can fill it with a degreasing liquid cleaner dissolved in hot water and leave it to soak for 5 to 10 minutes. Soaking will loosen the food residues and will make it easier to remove them. The quality of the cleaning liquid used determines how easy it is to remove food residues and fat. Make sure you use a cleaning liquid that can remove fat.
If there are fat stains on the pan or the basket and you have not been able to remove them with the cleaning liquid, use a more powerful liquid degreaser. Follow the instructions on the package.
