Static might be the issue, though discharges are usually intermittent. A constant "static-type noise" is rarely caused by that.
I wouldn't recommend Gruv-Glide without noting that it leaves a residue in the grooves, a residue which many find sonically undesirable. It's not clear from your post that static was actually your problem. Uncleaned biologicals in the grooves is a more likely explanation, especially if these records weren't cleaned with an enzyme-based solution. The Gruv Glide may have just covered up the problem. It's one of several record care products that behave that way, none of which will ever be used on my vinyl.
A safer way to test the static discharge theory would be to zap the suspect LP before/during play with a Zerostat.
