Hydrofluoric acid?! You can't be serious. That's one of the most dangerous substances in the world...to say nothing about the damage it would cause to paint and other parts of a vehicle.

Though I have to say...it would probably be extremely effective at removing calcium/other mineral deposits.

I reacted the same way on here several years ago but apparently it is/was true. I have no idea the concentration, but it is used in commercial car wash solutions.

It is also in some commercially available wheel cleaners, that part I did know about.

New window? If that's a side window, it's not that much...

The picture doesn't make them look too horrible to me personally. Do they impede vision?

Going to try more products today.

It does impede vision on rain or snow as it catched as kinda holds onto rain drips rather that then gliding down the glass. Hard to describe. It's like velcro to rain. And when dry is unsightly.

I'd try what Trav mentioned earlier and see if that works.

Also here are some good tips esp the Duragloss Nu-glass or the post from RtexasF about Bon Ami. Old thread alert:

I tried 0000 steel wool once and won't do it again. I found a few bits of steel wool that I must have missed in the cleanup settle down between some trim below the wipers and hood line rusted there. Luckily it wasn't there that long and I was able to wash/flush it out when I saw it. Bon Ami seemed to work better and I had no problems with tiny shards of steel wool rusting if I don't clean it up 100%.
