Sadly the photo doesn't do justice for the actual staining on the sills n frames.
This is a new customer who has recently moved into her new house. As I do a lot on the street, I was highly recommended and mentioned I can help remove or reduce this yellow staining on first clean.
However, I have faded it quite a bit compared to what it was like. (I didn't take a before picture as I didn't think I wud need to).
I've used magic erasers, Tfr and even white T-cut, all the stuff that has normally worked for me in the past. (yes, even concrete melting hot water 😂😂 before anyone suggests it
)
Yetithasnt shifted it fully. Its still shows a yellowish tint, enough for it to noticed. Anyone any ideas, or has it had it!
