A colleague at work asked me the other day! If you don’t know, it is a spray lubricant you can use around the home and with your motor vehicles and such.
Ohhh, WD40, yes I remember now I have in my storage. I use it on my car and many thing in my home also good for cleaning Aluminium!! Yes a spray lubricant, actually I used it on my cooker nobs the other day!! But I have no idea what the WD means???
