I think I have a small discovery that bears some research, and I thought I'd share with the DIYers that would like to try this. But it may end up having little or no value, and may destroy your records. Hence the research part. END DISCLAIMER
OK. We have an anti-static liquid that I use at work. I usually use it in a spray bottle, but it also is mixed with wax and put on the floor of our production facility and lab. Alas, the anti-static active ingredient is not on the label. One day, I noticed that it had a familiar smell. After a little brain racking, I remembered it - it was the smell of Bactine. Googling Bactine, I end up with the ingredient, benzalkonium chloride, a biocide that works great at killing little critters, such as the fungi that likes to eat plastic records.
Wait a sec - antistatic and antifungal? Sounds like a great combo for protecting records. I see possibly an aversion to surfactants. And what about residue? Luckily, it can be bought without adjuncts and diluted down greatly with water, and still maintain its properties. Food for thought.
