De-rusting metal parts with appliance descaler

I'm sure there are better ways to do this but this is what works for me - some cheap appliance descaler powder from the supermarket and a bit of hot water knocks the rust off metal parts very nicely. Coated/plated parts (such as the black or silver screws holding devices together) can end up being discoloured this way (stripped back to a dull grey) though I'll take a clean grey screw over a crusty brown one any day!
I was recording a few clips when attempting to repair a Sharp PC-1500 that's full of corrosion, it's a fairly dull set of videos so I just clipped out the most pertinent parts to make this (hopefully) slightly less dull one. All I really wanted to show was that yes, it does work...

hay that´s some interestin idea, i didn´t even knew that product existed, personally i was removing rust from a big piece made of metal sheet using vinegar since you can find evapo rust in my counstry. I don´t know how better is that in comparision, but the vinegar you need to clean fast before it leaves rust

How well does vinegar work for you? I was actually spurred onto editing this video together because someone on Reddit was looking for advice and wasn't having any luck with vinegar. I live in a hard water area and have to descale my kettle and shower head frequently so always have a box of powder under the sink - I find it works better than vinegar for descaling (not sure about de-rusting) and doesn't make my kitchen smell like a chip shop.

@@benryves well I don't know exactly, but looks like descaler is faster. Also vinegar evaporates faster since is alcohol based, so you need to cover with a plastic film
