I've got 3 white splodges on my roof. I've tried autoglym cleaner, it cleared up the lighter areas but I can't seem to shift the more concentrated areas. I've no idea what they are as they were there when I bought the car. I'm guessing bird crap that wasn't cleaned off quick enough.

Any suggestions?

Scrub with a stiff short hair brush (nail brush should be fine if you dont have detail brushes) with plenty of soapy water, then treat with Autoglym Bumper care applied with a sponge to bring back the black and seal it.

Bada Bing!

Yep, a good stiff bristled brush should clear that sort of stuff.

Great I'll give that a go. I would have thought a stiff brush would be too harsh but I'll give it a go

I haven't any experience of a similar problem, but having used 303 protectant for the vinyl roof and been very pleased with the results, I personally would have a go with the 303 Vinyl Convertible Top Cleaner and a brush.
The only links I can provide for this are

Bird lime by the look of it. I'm with the others. Use your favorite cleaner with a small brush. It might take a few goes. Then when clean seal the surface with your favorite protector.

Personally I use Ragg Topp for Vinyl (cleaner and protector) but it's up to you what you choose. Note the Autoglym roof kit is for FABRIC roofs so not suitable on the S2000. The Autoglym bumper care is fine though as a sealer.
