New to Orchid board. Question about transferring to S/H

[dr_orchid_lady]

Hi all. Relatively new to orchids, but have done a TON of research and decided to try S/H for my first re-potting. Transferred a sad phal from the store container to S/H with hydroton. However, when cleaning the roots, I couldn't get off every bit of dirt and I didn't want to scrub hard and damage the good roots. The plant is potted now, but I wanted to ask if there was anything I should have done differently? I will try to flush extra since there is organic debris still in there and I don't want root rot.

Tips?

Thanks!
