The sponge then holds bacteria surely?
Wilko's do something very similar without the brand name 50p a pack
Not much of a deal, around its usual Amazon price. It occasionally shoots up to a ridiculous price for very short periods to make this look like a deal. No need to rush in on this one.
Or save the environment and buy tesco own detol spray for. 79p and a sponge
Normally cheaper than this.
