Keep your brush clean!
Hybrid brush has been made for maintenance/spring cleans; it does have the benefit of excellent scrubbing with the Boars Hair, so can be used of first cleans, but you need to keep the brush clean for speed, that really applies to any make of brush to get the best out of it.
(If the first clean is very bad, consider using a alternative brush first, really quickly with a good water flow to remove most of the grime, keeping your main brush as clean as possible is always a good thing)
If you get any oily road grime on the brush when doing a first clean give it a quick clean with a detergent, small amount will do, only takes a few minutes in the back of the van. This will remove the oily deposit less chance with spotting on your next job and you can work quickly and be confident of your results. (or keep as spare brush in the van)
