1974 c3 convertible - original windshield

Going to try to attach a pic here that hopefully gives you an idea what im dealing with but i have a decent amount of spotting on my windshield towards the bottom (close to where it meets the dash).
I believe the spotting is on the inside. I have tried various products thinking maybe it was armor all type product that was left on windshield from spraying dash and baked from sun.
Is there any way to get some improvement short of swapping the windshield itself ?

Worth trying a very fine polish. Could be hard water spots. They also sell a specific windshield polish you can search anyone of the vendors here. Next step would be to find a glass sealant from the same vendor to prevent them from occurring again.

It does look like some type of dressing that you may have put on your dash.
Did you try rubbing alcohol?

The Glass Wizard cleaning tool has a unique net type covering that might offer a little more scrubbing power. I also might consider using a glass clay after covering the entire dash with a towel. I would be hesitant to recommend an action glass polish for use inside the car ... if you do, test a small hidden area first.

I should have qualified my statement. Looks like it would be on the outside. Droplets looked too big, to me, for a dash treatment spray. Inside a different story, my bad. Of course no sealing interior windshield.

i didnt realize rubbing alcohol had an effect on glass. Thats easy enough to try first.
On this glass clay product- does it require a good deal of scrubbing/buffing ? That area of the glass is a bit harder to reach easily given its proximity to the dash top

If the spots are on the outside that certainly offers a lot of choices indeed. Everything from glass clay, to glass restoring cleaner, to a glass polish. Often times these spots can be from environmental items or from minerals in the water. I use McKee's 37 Glass Restorer every couple months on my cars, it is designed to clean glass and has only very light abrasives.


As for the clay, you would need to hold the clay as well as spritz the glass with lube. You would want to do so outside of direct heat and cover the dash well. Its not the most opportune choice. That said if these spots bug you that much, you will work at it until a solution is found. I know I would ....

can try 000-000 fine steel wool and some white vinegar, thats always worked for me in the past on spotted or rain etched glass

Don't leave us hanging. What worked for you?

Distilled White vinegar with a microfiber cloth will take out hard water stains without harming anything. Follow up with another water dampened cloth.
see video ps: I tried it on my car and it does work. EZ PZ

White Vinegar and Water Spot Removing products often work best and offer the best success on recent spots. The challenge is that in the hot sun, whatever (minerals etc.) are in the spots can etch the painted surface. This is why it is important to protect paint and to remove spots when possible. I have seen spots that need heavy compounding and even wet-sanding to remove.

Apologies for not replying sooner, but work had me away from trying to tackle this.

So today i tried the following (in sequence)
1) 0000 Steel wool by itself
2) rubbing alcohol and MF towel
3) Distilled vinegar and MF towel
4) Distilled vinegar on 0000 Steel wool, followed my MF towel

Spots still there however....
thoughts on next steps ?
i believe these spots are on inside of windshield (but can't prove because i can't seem to cut into the spots to confirm)

Well...you tried many options and still have Autogeek as a resource.

My .02.......

Get a jeweler's magnifier or like and take a close up look at the glass to try to determine whether the spot is on the glass or in between (inside) the glass.

Also try to determine if the spots are on the outside of the car or the inside. Acid rain vs. interior cleaner.

Machine polish. Dermal tool or full size as required. Hand polishing failed to solve.

Good luck.

I have some Griots glass clay on the way from Autogeek.
Given the proximity of these spots to the dashboard- any pointers on hiw to apply this to the interior if my windshield? Does the clay require firm pressure or just friction ?

JoeD-C8

You can use a specific lube spray or just some soapy water, goes without saying to protect your dash. If your clay starts to drag on glass add more lube. I wouldn't say firm pressure, since you are applying it on an upward angled surface probably enough pressure to keep contact with windshield should do it. Good Luck!

JoeD-C8

I was just looking more closely at the cutoff line of the spots and they appear to be along the line of the inside of the dash. I wonder if a cleaner/treatment was applied and then sun baked spots in as the OP said. Maybe a quick contact to the Armour all folks?

6000 grit Micro Mesh cloth will remove the spots. Use a little water as a lube. I use a chock board eraser as a backing. Expensive but it works hands down.
