4. Simoniz Bug Shifter

Best price: 4.99 (Halfords)
Capacity: 500ml
Type: Spray

For: A good performer
Against:Not good enough when compared with cheaper rivals
Overall:

Effectiveness:
It produced a good finish, but needed two applications to remove the most stubborn of dried insects.

Buying:
This spray sits mid-table for price, and although it works well, it's no better than cheaper products.

Ease of Use:
Easy to use, but requires a few minutes for the product to take effect, and can need a second application for really tough bugs.

Special features/Limitations:
The spray is safe to use on all surfaces, but it's not recommended for anything other than insect deposits and bird droppings.
