Yes I trampled it lol. I was trying to get other angles to see if it changed by light.
Sorry D-Brown proI’d ty Brown Out from Harvard, buff with a red/white pad.
I have something called brown out and as far as I know it is very effective product, I will have that with me as well. Which ever it works I will use that.Sorry D-Brown pro
I will try a normal stain removal 9-9.5ph first on a small 1 inch area and see if that moves it or not. Then I will continue according.Don't go crazy bouncing your ph. Vinegar is an acid but I agree with the rust and whatever contaminants were trapped in your lines. In other words try to get your ph back to an acceptable level. Acid will set some stains.
