wire brush and a heat gun might be sufficient but i belive the chemical you're looking for is dichloromethane, which was banned by the EU as it's remarkably bad for your health (https://premiumdoorstripping.co.uk/dangers-dichloromethane-paint-strippers/)

That stuff looks well reviewed, and a little less deadly

I’m currently in the process of removing paint from my front wall with Stripaway 7. I think it’d cope with that step pretty easily.
Another cheaper option (that I’ve not tried yet but will at the weekend) is to mix your own lye with Caustic soda, water and wallpaper paste.Edit to @rogan for your front door.
Stripaway is available in 2 versions - no 1 for old lead based paints, no 7 for modern paints. You can get a tester with both if you’re not sure what paint you gave.
Removing paint from this doorstep any recommendations for paint stripper? Tried BIN stuff but still lots of paint stuck hard.
