Windows after house wash

Residential
1

Hi Everyone,

I washed a house last week on a really hot day and I guess that I either didn’t rinse the windows off thoroughly enough or I waited too long to rinse them.

I was using a combination of sodium hypochlorite and dish washing liquid.

The customer called me back and showed me that from the inside of the house, the windows had been quite badly stained by the house washing mix.

It’s been a week and a half since I washed the house so whatever the stain is has been there a while with many hot days for it to bake in on.

I said I’d go back in 2 days time to clean the windows - my plan was to use 1 part vinegar 1 part water and scrub the windows. I’m worried that this may not work.

I’m quite stressed out about this so I’d love to hear if anyone has had the same issue and how they recommend that I fix it?

I’m unsure if the stain is primarily the dish washing liquid or bleach or a combination.

Thanks! Would really love to get some advice.

If you don’t know how to clean windows professionally you may want to contact a local cleaner that can do it. Those smears can be a bear to get off.

If you’re collecting money from people and pitching yourself as a professional business… ditch the laundry soap and buy a designated surfactant. Majority use Elemenator, but there are other options as well.

That spotting could also be from the tds levels in the water.

It happens occasionally using dish washing liquid in my experience no matter what
