The first image shows a New filter basket.

Unfortunately the use of some aftermarket Petrol additives or cleaning chemicals can cause damage to the injectors, the chemicals being so corrosive the can dissolve the filter baskets

located within the injectors themselves, most manufacturers warn against the use of additives in your fuel and many void warranty's as a result of their use.

This picture shows the build up of dirt caught by the injectors filter basket, After the main fuel filter, just imagine the damage that could be caused if a cleaning chemical 

had already damaged the basket allowing the dirt to get inside the injector instead of being caught by the filter basket.
