Some of the brands for household/diy Silicone offer a 'Silicone remover' based upon ptsa, (paratoluene sulphonic acid).
Cartridge silicone has poor unprimed adhesion to common building substrates, poor tear resistance and poor wear resistance, (walking on it will quickly wear through it).
If you can find a cartridge of '1-part Polysulphide' in a builders' merchant that will have better tear and wear resistance, but if you have a wide, deep joint it will take a while to skin over and fully cure at the current low temperatures.
The Soudal FixAll, (ToolStation 84704) will be easier to find and will be better than the silicone.

What's the best way to remove silicone from plastic?
And as a follow up is silicone the best thing to finish the edge between the door trim and step?
Background:
The door fitter discovered part of the doorstep was fucked and missing. We said it was going to get replaced eventually, so the installer went crazy with the silicone as a temp solution until the step was replaced.
