Removing whitewash off of red brick

[cmturner 14]

I have a customer that wants the whitewash lightened on their redbrick. I am guessing that the previous homeowners had it done pretty white, well now this lady wants more of the red brick to shine through. Any ideas would be greatly appreciated. I have 4gpm, 4000psi and hot water. This is a first for me I haven't ever had a request for this one.

Isn't whitewash just lime? (calcium carbonate) water and a little pressure should be able to feather it out fairly easy.

Here is a photo of it. I am starting to think that I might pass on this. Seems like it might be a super pain to maintain consistency on the house.

Whitewash and strong 12.5% are not friends. Spraying all that brick down with a strong mix should melt that whitewash right off. Give it a try on a small area before you give up. I've removed whitewash before( without trying. Oops!). Use a Delevan or sureflow to apply it with. ds'ing won't be strong enough. I would also add a surfactant and maybe a bit of sodium hydroxide in with the mix.
