I use the same formula and temperature range (after lots of experimentation) but recently started to dry my records by vacuum... improved the Noise Floor and drying time but greatly increased the effort required to achieve maximal results.
Ultrasonic cleaning
How many of you are ultrasonic cleaning your records and what solution are you using? I have a Kirmuss ultrasonic machine and I am currently using Tergikleen solution with distilled water. Have some Audio Intelligence ultrasonic solution on order to try. I can tell a big difference with noisy records lowering the noise floor.
