To wet a patch with Ed's Red, without it getting too soaked, I tried using a roll on deodorant bottle, rolling it over the patch in the palm of my hand, but that doesn't work too well as it doesn't dispense enough.
So I looked around for something else and came up with these little pump dispenser bottles for manicurists/nail technicians to use to soak their nail polish removal swabs with acetone.
Works great!!
And cost me all of $2.84 for 2 of them, inc postage (Ebay item 261083579137)
You can get much larger bottles as well, but I got the smaller ones as I doubt they seal well enough to prevent evaporation; it still holds plenty for dozens of patches.
