I've been mostly working at startups since I graduated and I haven't had a job for longer than 2 years once I stopped delivering pizza for Papa John's and driving for Lyft. My pay is pretty good but it's kinda balanced out by the amount of time I've been unemployed.
I think if you sprinkle a little baking soda in there that could help with some of the more stubborn stains but vinegar alone works really well. I recently cleaned all the hard water stains off my sliding glass shower door with it.
