Chaps
Just done my first track day in the sprint at Snetterton 
so now got to clean off all the Cr**. Muk-off works well on the wheels but can you tell me whats the best stuff to get the rubber off the side pods 
Tried a few things and the car has got the film, then its all the dead bugs
I did mine the other day and used acetone (carefully!)
Autoglym Tar Remover works well.
Johnsons baby wipes. Not the supermarket own brand.
Brake cleaner
T Cut works well on mine to get rid of tyre rubber, the guys that valet my cars showed me that trick 
brake cleaner,
petrol
are the cheapest solutions and very effective.
You can then go to the AG etc stuff at twice the price.
I use Race Glaze as I get it free from the race team as we have to get the rubber marks off after every session.
