Best price: £1.25 (ebay shop)
Capacity: n/a
Type: Sponge with one abrasive side
For: Quite good, cheap
Against:Not as effective as other pads
Overall:
Effectiveness: The rough side of the sponge looked like it would scratch paintwork, but fortunately it didn't. It did, however, cut through dried-on insects with only water. Does not buff to a shine without a spray and would be better used with a liquid remover for an effective cleaning combination.
Buying: Cheapest product on test, but not widely available.
Ease of Use: Straightforward and relatively quick even, without a spray.
Special features/Limitations: Safe to use on all finishes and in dealing with a range of surface deposits.
