Ok my frier has a lid that covers it all up. I use mainly for twice fried chips. However I deep fry croquettes and samosas. Or fresh fish. I clean out by pouring through muslin especially after croquettes as the crumbs seem to stay in the frier. Hardly ever replace as last time I topped it up it was nearly 2 litres. I also make fried chicken southern style with bread crumbs.

When we had our deep fryer it sat out on the balcony all the time. We changed out the oil when it looked dark or if we cooked fish. Sometimes it would be in there for a couple of months.
Good. I'm now feeling more confident to fill it up with oil and leave it between uses, filtering if necessary.
