That acid can eat through important parts of your system you would never want to have to replace... like your evaporator under your dash.
There is a long AC thread that used to be a sticky..... if you search for ' flush' using my name in the advanced search it should show up. I think 80,000 something views.

Please define "high idle'.
No moisture will be sucked into the system when charging due to the higher pressure in the system than atmospheric. Moisture would only get in when the system has a hole and was depleted. Whatever moisture was there will still be there. That is why you need to vacuum the A/C for a new or opened system.
Any rpm would be OK. I don't think it makes any difference except in time. Do whatever you been doing if it works.
