Hi, it’s been a while but wanted to update. I ended up rewashing with about a 2% mix, let it dwell and then rinsed like crazy but it still essentially looks the same. New images attached. Do you think the mix wasn’t hot enough? FWIW, it seems to be pretty badly oxidized as this side is always in the bright sun and when i rub my finger, a good amount shows up on my finger.
Assuming a hotter mix/dwell/rinse/rinse/rinse doesn’t do anything to help it, what are my options? Is it basically just time to get a brush and manually scrub? It’s not a huge area so I don’t mind manually scrubbing if that will take care of it.
FYI, this is my parents house so it’s not a huge deal (they don’t seem to care at all), but I really would like to fix it for them (really bothers me every time I pull up to their house). Also, I see it as a good learning experience because as I was researching more about getting into this business, oxidation was one of the things that scared me the most. So now I get to see what seems like a pretty bad case first hand and would love to see thru resolving it.
Any thoughts/suggestions would be really appreciated?
