My neighbor had her patio stand replastered by contractors. Its the white to the left. I do not know what they used. They first added some wiring and then mixed something in a can and the left side is the result. I don't know if it was cement mixed with some special paint is my guess. The result is that they left my side in certain spots 'whitish'. The original is the darker grey. I told the neighbor and she said she sees nothing different, but I do. She has been a wonderful neighbor so I do not want any animosity between us. Since the job, it has rained numerous times, I hosed it down and what you see is the result. Does anyone know how i can get rid of that white stuff, other than buying expensive stuff...ie power washer?

Hi,
Ready to use stucco mix? They dry hard and stuck wherever it is
splashed. If that's case, afraid it won't wash off.

You can use some muriatic acid but it'll age with time and blend in
anyway so I'd not worry about it.

Call the contractors and insist that they come back and clean up after themselves. If they
refuse, call a lawyer.

Or if you think that's too much hassle or expense, you might try washing the entire area with
vinegar.

The picture is sideways, so hard to see how much it shows; between fence
and back of house? I'm pretty obsessive, but it doesn't look much worth
worrying about. I'd try scrubbing with vinegar and a brush before I'd
think about muriatic....don't want muriatic on the AC.

Tell your neighbor you need to get an estimate on some work, get the contractor's name and have them come over and tell you how to fix the problem. If they are smart they will fix it. If they are stupid, they will tell you how you can fix it.

Threatening the contractor or talking about lawsuits is a stupid idea for something this minor. If the contractor won't work with you, hire someone else or just paint it.

It'll wash... :) Plus, it's not hard on metal but would do a number on
shrubbery, etc., ...

I'd try vinegar. Spray in on and allow to set, then wash it off.
Sulfamic acid is another choice - used on tile as grout and haze
cleaner (by Tile Lab comes in crystals form you mix with water.

Sulfamic acid works like muriatic, but is much milder.

No offense, but the photo server for the picture did not set it right. I did and they screwed up...that said, most people know how to copy such a picture and have it turned the right way in one of their photo programs...we all have one of them. I do not know if it could be done here in this forum..but if its too much trouble than just don't bother.

My own personal feeling is that vinegar MIGHT work, but my guess is that it'd be too mild of an acid to dissolve the stucco or plaster. Muriatic acid, on the other hand, is like breaking an egg with a sledge hammer.

I would try CLR or Limeaway or a Phosphoric acid based toilet bowl cleaner. When doing this kind of work, time is your friend. Put the acid on and give it plenty of time to work. Then clean the acid off, allow to dry, and then apply acid again. You should see a reduction in the amount of stucco or plaster on the surface with each application of acid.
