I’m gutted! I’ve been off my feet for a few weeks after a skiing accident and in that time the condensation built up and I now have mildew on the inside of the softop (sierra).

I tried a white vinegar solution (3/1) but the black dots are still there.

Can anyone offer any help.

Picture just for attention.

Here's a few recommendations I'm copying and pasting:
  • Combine baking soda with water to create a paste. Apply it to the affected areas and let it sit for about 10-15 minutes before scrubbing gently with a soft brush. Rinse with clean water and let it dry completely.
  • A solution of hydrogen peroxide (3% concentration) can be effective against mildew. Apply it directly to the spots, let it sit for a bit, then scrub and rinse.
  • If possible, park your vehicle in direct sunlight for a few hours. UV light can help kill mold and mildew spores and aid in drying out any moisture.
Once you’ve cleaned it up, consider taking steps to prevent future moisture buildup. A dehumidifier inside your vehicle can help with this.

Make sure your softop dries completely after cleaning and before reusing it. Good luck, and I hope you’re back on your feet soon!

You said "lack dots" so is that mildew or is it mold?

My convertible had mildew all over the vinyl interior and I cleaned it with 409 and a sponge. If you have mold, I think that requires a different cleaning method.

That’s brilliant, thank you. I’ll give it a go and see how I get on. As far as an in car dehumidifier, I’ve not been able to find one other than the silica packs.
