These days, we hardly fry our fish as we find it time-consuming and messy with the oil splatters.
Instead, we grill our fish using the oven and it is way healthier, as very little or no oil is used.
To remove the aftermath of fishy odor from the oven, we put fresh orange or lemon peel in the oven while it is still hot - the moment the fish is cooked and removed from the oven. You can turn off the heat and close the oven door with the orange or lemon peel inside.
After a few hours, the oven will smell zesty and refreshing. I then use some wet wipes (I rinse the clean wet wipes under tap water to wash away any chemical in the wet wipes) to wipe away the grease inside the oven and let it dry with the oven door opened.
So the next time you eat an orange or make a glass of lemonade, don't bin the rind. Save the orange and lemon rind to freshen up your oven after use. It does not cost you a sen and your oven smells great after use. This way, you don't have to use chemical-laden detergent to clean your oven. But make sure that you use fresh orange and lemon rinds and not dried ones aged a day or two ya. Fresh rinds emit a fresher zesty smell :)
Oh yes, I love to use orange and lemon rinds to wash greasy dishes. The dishes smell great and I only have to squirt a drop or two of dishwashing liquid to form some foam to wash up.
