In recent years always used gardiners.
Have been using an extreme dual trim medium for the last year or so.
Not overly impressed by its scrubbing power on birds mess.
What do you suggest for good scrubbing power ?, on my round, spring always sees an increase in nesting gulls with young and more bird poo.
Notice G's now do a hybrid brush with mono outer bristles and flocked inner, are they any good ?
