waterspots after rain

It rained a few days ago and today i washed the car and after drying it i noticed these water spots on the front bumper,
can these water spots be removed safely with a clay-bar? or do i need to take the car to a professional detailer?

If they are indeed water spots then distilled water will rinse them away. A clay bar is used for picking pulling asperities out of the surface of the clear coat or paint after it has been thoroughly cleaned.

The image does not look like my water spots. My well water is very very hard, so I rinse with a gallon of distilled water.

Rubbing alcohol may work on those.

In the US ‘rubbing alcohol’ is a isopropanol solution in water, typically 10% - 30% water.

Yes that is correct. At times my car also has similar marks as picture in post#1, and they may be tree saps and such, and rubbing alcohol works better than just water on those.

That is not the intended use purpose of clay bar. Clay bar properly used is sticky adhesive and hydrodynamically glides on the lubricant and should touch only trash that sticks up through the lubricant, sticking to it and pulling it out of the paint / clear coat.

That's not water spots at all, in my opinion. I've had that before - it's bird poop stains. Some call it etching. All it takes is some bird poop sitting on the paint for a bit. But what's interesting is that it's not all bird poop. And sometimes you don't see the stains until the car is clean. Anyway, I tried everything and eventually had a mobile detailer come out and use some sort of buffing machine to fix it. I used compound, alcohol, lots of soap, and it only was removed by the professional.

Anytime you polish away paint damage, you should start with the mildest product and then work up as necessary. The first thing to try is a cleaner wax. If you have a good coat of wax on the car, you might be in luck and the damage is to the wax and not to the clear coat.

I wax the top of my cars (door handles and up), the nose (everything forward of the front axle), and the top of the back bumper twice or three times as often as the sides of the car. Those surfaces get the brunt of sunlight, bug, and bird poop damage.

Frau Putzer brought a banged up Civic to the marriage. It looked like it'd been parked on a war zone. There was some bird poop on it once. As an experiment, I left it there to see if/when she'd wash it off. She never did, and when I cleaned it off it had ate down to the primer.

my car doesn't have any waxes, never put anything on the car, i just wash it with regular car washing products.
i'm not really worried about these spots im just curious if they can cause permanent damage.
at this point my car isn't worth my time, the car was in an accident last year and i can never look at the car and see the car i once had, i wish it was just totaled and i got rid of it back then, but oh well..
