I cleaned the vinyl siding for 3 buildings of a condo association. They were super happy - I was super happy. They said I can come do it every year and then this …
Downstream mix was 2 gallons weak bleach, 3 gallons water and Elimonator. I rinsed everything well (I thought.) Condo Association was super happy but then just got a call about roof vents. The tops are all discolored. These are highly visible and I don’t know what to do. I just scrubbed with dish soap and water and nothing changed.
Do you know what caused this? Any products that can fix it? Please tell me ASAP as I want to solve this quick. Thank you very much for any help!
Thanks so much!! I used boiled linseed oil and mineral spirits and it restored the old color (mostly). It was an easy fix but I was definitely worried about it. Thanks very much for your quick response. Here’s the after photo.
