It's mid August and slime and weed are slowing us down. Not drastically but taking the edge off performance. A lift and scrub is expensive considering the time left this season and we are too extreme to dry out safely. So, should I just clean/scrub the worst bits I can get too? This will inevitably thin the paint coating in what has already proved to be the most vulnerable areas and may lead to accelerated further growth. Or is it better to accept the reduced performance and leave well alone?
