1960's house so the boards likely contain asbestos, Originally painted with oil based paint then later with acrylic. Oil based paint has cracked & is peeling off so we'd like to remove as much as we can. Water blaster not doing the job well enough. DH tried a wire wheel on a grinder but the acrylic paint is just melting into this & clogging. Any suggestions please!

Spot prime, fill, sand paint over, done. Why your trying to completely strip them is beyond me.

If the soffit boards likely contain asbestos you should NOT be waterblasting them (it's illegal). Likewise you don't want to be using any machinery on it which is going to create fine dust. Hand tools only.

Actually, sanding asbestos without proper dust extracting machinery is more harmful to health (and potentially illegal) due to the possible inhalation of asbestos containing dust, than waterblasting asbestos which dampens it thus making the possiblity inhalation non-exsistant. Did you know that the most common method of asbestos disposal is actually in landfill! Reason! Because the earth keeps it damp! Other method! Incinerate it at 1250 celcius until it turns to a silicate glass.
Reason for removing it! It's flaking off - right back to the Hardie board (or whatever it is). Oil based paint does not stick to Hardie Board, but acrylic does. If we just slap more acrylic over the exsisting, then we're going to have this issue again & again, but by removing the base oil paint, it's unlikely.

I've read it more than once. here is one resource.
Ah ha i saw it on the internet so it must be true!
There terminology is off it is not illegal but it is restricted work, dependant upon the type of asbestos you need to be certified to remove it.

Yeah I know, it wasn't a hugely credible source (just one I could find quickly).
I was sure I'd read it somewhere else too but I haven't been able to find anything in the Department of Labour and Ministry of Health resources I've been using. Either way, their guidelines are all consistently clear: do not use high pressure water or jets on asbestos and no abrasive cutting or sanding tools.
I feel for OP though. I'm relieved that our soffits look like they're wood!

Use a stripper there are some good user friendly ones like SPC sea 2 sky 202 and scrape off, dont sand or waterblast it your life is worth more than nice looking soffits. Prime with an oil based pigmented sealer and apply 2 -3 coats of good quality acrylic paint
