You can, but an oil based cleaner would be better. I use WD40.
in longboarding bearings don't make that much difference (providing they are clean and oiled) unless you are racing slalom or downhill were every 0.001 of a second counts. so cheap well made easy to clean bearings are the best e.g. bones reds or bilitins are great simple to clean and change.
mostly wd40 but on a rare occasion you can use a sponge
