For a few weeks i think we should go for a total ban to really try and get soem additive out of the carpet, but in the long run as others have said that might not be very easy as if someone is struggling they will just slap on abit of additive and jobs done and without having someone to check tyres before every run no1 will know.

Allowing specific types of additive that will help the carpet clean up is easier to police with spot checks if really required.

Apparently running just the additives above would really improve the carpet and stop the problem we are having but i do think we need to try without anything for a week or two to fast-track the carpet cleaning as it is abit soaked atm.
