You can still buy old fashioned Brasso metal polish -- the kind that works really well -- in the EU, but it has been outlawed in the US for over a decade. We have to make do with a less volatile version that, in my experience, is inferior to home made cleaners.
And as I found out when I had a cold, as a result of replacing pseudoephedrine with phenylephrine then OTC cold medicine like Sufaded no longer works. Druggies were using pseudoephedrine in the illicit manufacture of methamphetamine. You now need a prescription for medicine with it. https://www.forbes.com/sites/daviddisalvo/2015/10/26/the-popular-over-the-counter-cold-medicine-that-science-says-doesnt-work/#2cce26a04753
