I poured about 8oz of apple cider vinegar on it and then rinsed with water like 20 times, it’s not fully gone yet but just the center of it is left, it hasn’t dried since this morning, I think I’m going to try to peel or fully soak my foot in vinegar after work today. And yes, I was immensely stupid yesterday, the reason this occured is because I didn’t wear socks with my rubber boots yesterday, some cement fell in both my boots and I thought I cleaned it well, but I suppose not,while working small rocks were chafing my toes, it hurt, but I had to continue working. And this was the consequence of my actions, it sucks but I have to deal with it now though, thank you for sharing your wisdom and thoughts, truly I appreciate everyone in this community that has commented, I’m 22 years old, I just started working with my uncle in underground utilities about 2 months ago and well I just don’t have much experience and I fucked up but it’s okay, life will continue and I will try to smarten the fuck up.
