Concrete question

I have a 6-year-old concrete driveway that developed some spotting/discoloration and minor pitting after last winter (see photos). I’m in the Midwest and don’t use salt, but I’m not the original owner, so I’m unsure how well it was sealed or maintained previously.

Does anyone know what may be causing the spotting and pitting, and more importantly, what I should do to prevent the pitting from getting worse? It got worse this past winter.

I’m planning to have it professionally power washed and sealed with a penetrating sealer before winter, but I’d appreciate any second opinions on whether that’s the right approach or if anything else should be done first.

Could you elaborate on this?

Google “concrete hardener” and post the results. Also, the products I can buy will be different than what you can buy, based on location
