SME 20/2 Static Electricity

The newest version of the Audioquest record brush is grounded via your body; the bristles are in electrical contact with the handle.  I have found that this works pretty well to dispel static charge in the process of wiping an LP before play.  All the other cures and preventatives mentioned here probably have one degree or another of benefit.  My own biases make me skeptical about Gruv Glide or any other spray used anywhere near my LPs or equipment. That's just my personal opinion, and I don't believe such sprays are essential in view of the other available options.

My advise for the grounding mat is an easy one, it only cost 15.00 and no need to spray anything or buy a humidifier. It is a no brainer. In the 7 years I have used it, I have never had a problem with static zapping my system. I cut the mat down to 3" by 3" and have it sticking out from under the turntable at the top of my audio rack.  It is held down by 3M double sided tape and does not move but is easily removable.

Just get one of these:

My solution cost $15.00 and works, how much does the vinyl ionizer  contraption cost?

Another joke. Lewm, I'm on your side on this one. Spraying anything on your record is a bad idea and it will not stop the static problem neither will grounded mats. A mat will only discharge one side of the record, the wrong side. There is no magic in this. You have to have a path to ground from the site that the static is being produced. The stylus in the groove. Static electricity is terrible for records because it draws dust like a magnet which you can prove to yourself by holding a record you just played up to a light and you will see dust fly towards the record. The dust can become embedded in the groove and held there so your stylus can grind it into the groove instead of pushing it out of the way. Besides the grounded sweep arm the next best thing for record hygiene is a dust cover. 
By the way take a meter and see if your "grounded mat" is actually conductive. If it is not it would even discharge the side of the record touching it.
