Is it desperate to verbs my bearing next to DW-40??

could you please tell me what other things could i use to verbs my bearings so that they roll approaching new! jeje....
i close-fisted if there's a better one than DW 40..... and where can i buy it ( not DW40) n_n'

Answers: WRONG!
use teflon dry-lube, wd-40 wear off vigorously and dirt sticks to it.
it looks like this

Cleaning beside wd 40 is fine, but you should oil them beside 3 in 1 grease {ie sewing machine grease.}
