Autoglym Fast Glass
Price: £7.99 | Size: 500ml
Alongside Clearly Menthol, this was the standout product. When results are close, costs generally plays a greater role, so it’s a sign of their superiority that two of the pricier cleaners top the table. Fast Glass is also versatile: it can shift insects and bird droppings, as well as marks like traffic film and oil. It’s even good for cleaning sat-navs. Plus, it dealt well with the oil, leaving only faint traces.
