Against:Takes a few minutes to work
There are faster-acting products, but when value is added into the equation, the Bug Blitz spray is hard to beat. As long as the liquid is left to soak into baked-on residue for a few minutes, this bright pink spray is effective. It also polishes well with kitchen roll or a cloth.
The cheapest liquid product by a long way, the next cheapest was nearly twice the price, volume for volume.
Ease of Use:
Easy to use, however, it takes a while to act and may need another application on thick residues.
Safe to use on a wide range of surfaces and debris.
