Went to wash the car yesterday and behold:

 

 

A big long streak of algae behind the top of the lens.

 

Tried to get a toothbruch in there but didn't even get close to touching it.  Anyone else had this?  Am I going to have to pop them out to clean or is there another way that anyone's tried?

I’m sure mine has this but not as much or as visible.

 

I think taking them out is the only way then you’ll be able to get to the back or be able to use a thin pipe cleaner

Looks like it's on an exposed edge before the seal? Personally I'd spray some bleach in there from above and call it done 

Yes. Mine does that. I take them out every summer and clean them. 

Cheers guys. Seems like a bit of a design flaw then!

 

Any tips on how to get them out? I've not worked on the Skoda at all before so am completely unfamiliar with it.

Remove the trim on either side of the fog lights. You will see the sections when you look at the lower grill. That reveals the screws to remove the fog lights. 

I use a product called wet & forget around the place to kill algae on the patio, walls, convertible car roof, boat, boat covers, shed, bins etc. Basically I spray everything with algae down once a year I usually give them and any other green bits from parking under trees a quick spray on my way past. One spray leave it to dry, looks a bit like a local cats pee'd on it until you next wash it but resist washing it for a little while, they clear up over a few weeks or so and stay clear for a year or so. Certainly until I next wet & forget a year later. Saves taking them out. Not worth buying just for the fog lights but I use it anyway as it saves a load of jet washing on everything else. Not found anything that it damages yet.

Thanks for the above and I've read about Wet and Forget and I think I'll try it.  There is some algae around the garden to shift, but on the car I have algae on the door seals.  One of the reviewers of the product says they've removed it from their door seals with this product.

A detailing brush and your favourite car shampoo mix will remove that as well. On the door seals, window surrounds etc. doesn’t need done weekly. Twice a year maybe.

 

Ive tried that Wet and Forget stuff on my patio. Didn’t do anything from my experience. Maybe try again at some point.
