The factory used a lithium based grease (spray aerosol is the easiest to apply), because it lasts extremely long, is resistant to temperature and dust, lubricates very well (most wheel bearings are also lubed with it) and the plastic slider is made from a material which is naturally resistant to it.
I googled Walmart's Super Tech General Purpose Grease, but could not find anything which said what it was made from. On the back of the label of the aerosol version it mentioned paraffin (wax).
It might be best to seek out something like this:
It would be about as close to the original as possible.
I would caution against using a silicone grease because, weird as it may sound, silicone can sometimes cause sticking issues, depending on the mating materials.
