Simoniz Bug Shifter
The maker doesn’t specify an exact time that you should leave Bug Shifter to work (it simply says “a few minutes”), so we tried it twice. When left for one minute, it wasn’t as effective as Turtle Wax, but when left for two minutes it shifted all our bugs.
The 500ml bottle is keenly priced – slotting between its two rivals – and you don’t need that much of the formula to clean large areas. Just be careful when spraying as the green liquid gets everywhere, and it’s not exactly discreet if you miss a spot.
