Detergents are basic because that works wonders on greasy stuff. When oil polymerises it won’t be susceptible to basic substances anymore but will react to acids. (Unlike acid and oils which don’t really react with each other – think vinaigrette separating in the fridge.)

Washing a cast iron pan with detergent will clean it from unpolymerised oil.

Cooking e.g. tomato based sauces in your cast iron pan will strip it of the polymerised coating (might impart flavour too).

Cleaning kitchen tiles near your stove is sometimes easier with acidic cleaning solutions as well. Just be careful with the caulking which will brittle over time from using acids.

Thank you, I’ll have to check it out!

I’d be interested to hear which book this was!

Thanks - I’ll have to look into this!

Not really no!

There was a “Multi Web Search” by Oleksandr for Firefox but it was last updated five years ago. It also intermingles the results whereas I would’ve liked to see them side by side (to compare how different search engines rank the sites)

The SearX feature the other guy mentioned might be the best bet!

Hah! It would seem so!

I would like two search engines displaying results side by side whenever I do a search. There’s so much empty space on a wide screen display anyway.

Maybe I should check if there’s an addon for this…
