Cleaning stucco house, including some rust

Both have green algae on stucco? are you just trolling at this point?
I told him he may need to go over some areas more than once (the darker areas) - which you said was poor information - please tell me how that is poor information?

I was initially responding to @EDM95 saying that DS’ing wouldn’t touch that, which is simply not true.

What are you going on about? I just showed you how I DS’d literally black on white stucco and it cleaned up just fine - while admitting that I did multiple applications and that it isn’t the most efficient way - even said he could do it faster with a dedicated pump - so once again, how is that bad information?

I don’t understand how you think I could be trolling… your photos don’t compare to the stains he is dealing with. The poor information is simply you telling him he can downstream this. I’m not gonna argue this as you are clearly mistaken and haven’t dealt with stains as heavy as this before.

Agreed, and yes I agree that x-jet/12V can get it done faster - but you can still DS that with good results

:man_facepalming:

ok, how about this one? is this one dirty enough?

Still doesn’t stand up to what he’s showing, but yes that is dirty. I’m not even gonna ask how many times you had to go over that if you had to go over that other building more than once. You can stop replying trying to prove your point though. Agree or not, I believe your advice is poor. Sorry.

12v would have cleaned that.

I don’t disagree with you. I DS stucco all the time. Some clean up better than others. I’ve hit some thinking there is no way this will cut it and I’m going to have to break out the 12v and surprisingly they actually clean up nicely. Granted, those pics he posted are pretty nasty, but I wouldn’t say that I completely disagree with you. To each his own. But having a 12v, I would probably go straight to it on those he originally posted.
