  • You’ve already got answers about rice so I won’t comment on that.

    Once you’ve noted the corroded places, clean it by using 99% isopropyl alcohol and an ESD brush. In lieu of an ESD brush, a regular toothbrush is usually fine but best practice is to adhere to ESD protocols.

    The main area you won’t be able to get to is the BGA underneath some of the ICs. To clean under there, the board would need to be put through an ultrasonic cleaner.

    I usually give any wet board 24 hours to dry with a fan circulating air over it, flipping the board around the 12 hour mark. Humidity is usually 30-60% where I live.














  • There will certainly be areas where the trail disappears, but tracking isn’t necessarily about locating every individual footfall.

    With an understanding of movement and behavior, one can make inferences about where the animal went to find and follow the next sign.

    Even moving over rock or packed soil, sign is left. You may not be able to perceive it yourself, but to someone who spends hours a day reading and studying the ground over the span of years, those subtle differences are perceptible.

    An animal will eventually reach a place to stop and rest, but with repeated interruption that rest won’t count for much.
