I washed my car twice thinking it was just dirt, but turns out these are hard water spots/scale and they’re not coming off at all.

Looks like they’ve baked into the paint a bit and regular wash did nothing.

I don’t have a garage or shaded area, so doing a full vinegar treatment isn’t really practical for me.

What products actually work for this that I can use outside (something I can grab from Canadian Tire or Walmart preferably)?

Also, at what point do these need polishing instead of just a chemical remover?

Any help appreciated.
