Xiekitchen,
Let's not forget that MD wants you to buy their brushes. I'm not saying they'd lie but they do have an incentive, FWIW.
I have scratched records with a dry Hunt EDA brush. That is easy to do. Be careful with that one.
I've *tried* to scratch them with a dry MD brush - vigorously - and it's not easy. It is possible though. All it takes is some grunge between brush and vinyl. But once the brush is wet vinyl damage does become very unlikely.
But IME hard scrubbing isn't beneficial, at least with RRL fluids. Gentle scrubbing works better than none, but there's no upside to going medieval on your records. It's important that the fibers carry the solution well down into the grooves, but that's about all.
