1920s front door - Best way to remove paint?

[WillowB]

I'm in the process of painting the original wooden front door of our house.
The actual door is fine but the frame has multiple layers of paint, some is peeling off revealing bare wood, bits of the wood are rotten - I'm not sure how to proceed?! I've given it a quick sand to get the flakiest bits off.
I've got a heat gun, paint stripper & a sander - which should I use?
TIA

I’d use a corse grain paper to really scratch the paint surface. Then stripper.

Wear a mask just in case the paint is old (lead based).

Or wait until after lockdown and take it to be dipped.

Thanks - I'm just waiting for the paint stripper to do it's job!

@WillowB which paint stripper did you use and did it work? I need to do the same but reviews I’ve found haven’t been promising for the brands you can buy in Wickes!

Caustic soda mixed in wallpaper paste is cheap and does the job. Loads of safety warnings obviously, but if you have a huge area to strip it’s perfect. I did all the doors and the handrail/spindle of a staircase in a 3 story house with this method. Wrapped it in cling film as I went to keep it wet.

You need gloves, mask, long sleeved top and bottoms while you do it, cos it burns. Obviously no pets or small people either.

I’ve never got on with stripper, I find it doesn’t work well and is very messy and more much hassle than a heat gun. The fumes off the heat gun are awful, but it does the job well and quickly.

Well I tried Wilkos paint stripper yesterday. Applied 3 thick coats & apart from a bit of bubbling in the surface there wasn't much of a result.
I'm going to try again with a heat gun (& mask!) later.
