My front indicators are looking a little tired, the 'veins' around the edges are filled with green crud.

Has anyone successfully cleared these?

i bought replacement depo ones, but they've misted up and will only go the same way. try splitting them with a heatgun, cleaning them then siliconing back together

I thought as much but we can try

I popped my ones out when I whipped the front bumper off to fit my splitter.

Pulled out the rubber strip, gave them a good clean (it came off like slime!) and re fitted.

On my ones it was just trapped gunk and didn't need anything taking apart.

Yep mine are the same, very annoying cleaned them out but cant get in to the light unit to clean the very edges.

The indicator units are a really crappy design. I've replaced one of mine because the lens pulled away from the reflector. The way they sit against the headlight units pushes on the lens and forces it apart.

Just buy a bulk load and replace them every few years!
