We have a sliding glass patio door that was getting squeaky and hard to push.
No problem. Just clean off the track and put a little bit of oil down, right?
So I went to the garage and got my handy-dandy can of WD40, sprayed it on the track . . .
THEN! I stood there with my handy-dandy little hand-held whisk broom and thought . . . If I use the whisk broom now, it will be covered in oil and I won't be able to use for anything else.
. . . I just did this backwards, didn't I.
