Hard to say anti bacterial activity

If I wanted to respond in a totally objective about the effectiveness of these wipes should have been able to pass a swab to rub it in a Petri dish and wait for the possible growth of bacteria.
Otherwise, it will be sufficient to pass the felt on objects that can be damaged by chlorine bleach, such as the wheel of the car and handles various affected by your inconsiderate guests who do not wash hands after using the toilet .... At least we will have done something. I put only 4 stars because the principle of wipes is not especially environmentally friendly and their use should be restricted where it is impossible to have anything at hand (in the car or motorcycle for example).
The mobile phone is known as the nest of germs present, this product without bleach should be perfectly suited.
