I used Fairy Power Spray on my cherries. It really stings.
Actually I did use it on my Cherry Paulsons. Spray it on, leave it on for maybe 30 seconds, rub the chip between your fingers and rinse it off. No long soaking. Works beautifully.
Not sure if you guys over there have Fairy Power spray. Its that BBQ cleaner stuff that comes in a spray bottle.
One warning though. After cleaning 100 chips, I was able to watch the top layer of skin peel off my fingers over the next few days. Maybe that's why they suggest you keep if off your hands.
