Sit back and relax whilst it does the job for you,
My kettle was getting pretty backed up with limescale and started to effect the taste of my tea so something had to be done, so I tried this Oust descaler which claims it gets rid of it within 10 minutes.
Pretty simple to use, fill your kettle up half way with water and make sure it's fully boiled, when it's boiled use scissors to cut a slit in the packaging as it's not easy tear and pour the descaler in slowly to avoid spilling it onto your skin as it's an irritant, then leave it for ten minutes (I would recommend opening a window to air out the room as it can spell rather chemically).
After 10 minutes the limescale should be completely gone (it was in my case), just make sure the contents are then poured out and give the kettle a really good rinse out with cold water, then refill the kettle and bring to the boil once more followed by another rinse and it should be rid of any chemicals.
I can't comment on how good it's with other appliances, but after seeing how well it removed the limescale from my kettle, I'm sure it will do just fine!
