Default Removing hard water spots from rubber molding

This past summer, I screwed up and let my irrigation system spray my car one morning. It was one of those lovely Texas mornings where the sun was able to bake the hard water (from a well) onto the car before 8:30am when I realized my mistake. Frustrating..

Anyway, I was able to fix the paint pretty easily with a porter cable and some super fine polish. I didn't think much of the rubber moldings at the time, but you can still see the water spots on them several months later.

Any recommendations for getting the hard water spots off the rubber moldings (around the windsheild, etc.)?

303 Aerospace Protectant? Might not do the trick, but it's worth a shot. I was trying to get my gauge rings cleaned up and went through two other products before using the 303, which did the trick. I wiped aggressively with a micro-fiber and very liberal use of product (basically soaking the rubber trim.) Like new.

I had these little white abrasions on my dash as well, tried the first two products and there wasn't much improvement,,, tried 303 and it looks like new. I don't know why, but the stuff is sort of magic. I bought an 8oz bottle first, as it was the only size available at the local West Marine. After the first detail using the stuff I promptly ordered a gallon.

If that doesn't work try 1Z Einszett Plastic Deep Cleaner or possibly a Claybar with liberal lube (I'd spot test an inconspicuous area.)

I just applied a regimine of Zaino Z2 and Z5 polish on my car and found that it left the rubber seals looking like new, clean, and quite natural with a slightest bit of gloss.

+1 on the 303

I just picked up a Mini and the poor thing had been molested by a sprinkler for a month.
The 303 did pretty well on the black plastic wheel arches but if I recall correctly I also used Mothers Back to Black.

I have a more expensive product... can't recall the name. anyhow, I didn't need it.

Thanks, I think I'll give the 303 a shot. Besides the boating stores, does anyone know who might carry this? Autozone? Pep Boys?

Wipe with some vinegar on a micro towel, then hit it with the 303.
