soda blasting paint off a brick wall

Hello Readers,
I'm trying to gather information on a project I planning in a couple of weeks.I want to strip paint that is flaking off an exterior wall.I have read some information on several methods of blasting the paint off but I,m leaning towards the soda-blasting method.So my question is,do you use regular baking soda that you can buy in bulk? Or is there one specifically for this purpose.
Thanks for any input.

I would just rent a 2 or 3,000 PSI pressure washer with a red tip. You don't need any soda.

Thanks for the response.
I plan on performing the blasting on my 3-flat here in Chicago.When I bought the house,the open porch had been painted with an industrial-type paint.Both,the masonry and the wooden members,were painted with this stuff.Thas why I was leaning towards using an aggresive method of removing this paint.I plan on replacing the floor boards and railings and a few other items,but I would like to clean and keep the 6x6's and other structural members.I would like to do this on weekends so I dont have to miss work.
Your suggestion sounds good.Will it remove all the paint on one pass? I would like to strip all the paint on one weekend.
thanks for your input

I would like to give you a guarantee that all of it will be removed but no one can be sure of that. I'm glad that you mentioned that part of it is wood because there is a danger of damaging it. If you see it tearing the wood, back up or use the green tip instead of red.

Thanks again for your input.
So if I rent a 2000-3000 psi pressure washer from the local rental yard,is this the same source where I can get the red and green tips.It it can be accomplished with just high pressure water,it would be ideal.
Thanks

Yes, the machines come with different tips but sometimes retal places don't provide a red tip unless you ask for it. A lot of damage can be done with them. I would try that first. If it doesn't do the job, ask them if there is a connection to the machine to add the soda solution or whatever else they suggest.

O.K.,Thanks
But if I do resort to using soda-blasting,do I buy baking soda like from a restaurant supply store? Thanks

Ask the guys at the tool rental place. Personally, I never heard of baking soda used for that.

I've seen soda blasting used when stripping vehicles for restoration...much less agressive than sand. Also friendlier to the enviroment for cleanup and such. Also less dust if I remember what they said right.

Thanks,
That is why I would rather use the soda-blasting method.When I was a kid,some neighbor had his 3-flat sandlasted by some hacks who didnt take any measures to try to contain the sandblasting.There was a lot of upset neighbors.One neihgbors gutter fell off because they were full of sand.
I would enclose the porch with tarps,but the little I couldnt contain wouldnt be that much of a detriment because its only baking soda.
