Shot blasting with a presure washer?

Neighbour bought one and it didn’t work all to well using the pressure washer to siphon it. I have since used it with a pressure pot blaster to force the sand down at 10psi and it works a lot better. Not sure how economical it is on sand mind. Have you not a local blaster that would blast them for £50.

I used a pressure washer with gritblast attachment years ago, it just sucked the grit in from a hose you popped in the grit bag.
Two things I thought were wrong with it, one you have a pressure washer with clouds of vapour and water splashing about everywhere and you have to try and keep the grit inside a shed away from the moisture or it just stops flowing.
And secondly if you get it all cleaned and blasted shiny then look ten minutes later there will be a nice golden brown rust sheen on the surface.
I wouldn't bother trying to combine the operations, just pressure wash the worst of the crud off then get it gritblasted properly somewhere.

Where are you located ? We have a proper industrial blaster, mobile compressor and air fed suit we hire out

Two opposite ends imo, a sand/shot blaster is to get down to bare metal, rust free. So the idea of adding water from a pressure washer to the mix is against what the blaster is trying to achieve.
You could argue that if the water was hot it would kinda steam & evaporate off, but be hard to see what you are at with all the steam.

Wet blasting with soda is a thing now. Growing ever more popular. More environmentally friendly, less distortion in thin metal as the friction is reduced and a lot cleaner as the dust is suppressed. Bicarbonate soda leaves a residue on the panel that protects it from oxidation so the rust isn’t an issue unlike with sand and a power washer.

My Karcher came with a dirtblaster as well as the standard lance. I had a pair of old up and over garage doors that I had cut down and made into a pair of hinged doors. They had 2 layers of old paint on them that the dirtblaster removed totally. The bonus was that under the paint was a galvanized finish, so they didn't need painting.
I'm not sure what the dirtblaster would do with rusted metal.
