I wouldn't do something based on someone else doing it on youtube. A lubricant that is wet and sticky will hold on to dust and any other crap that falls on the record and that cannot be good. Last is just the opposite. It is dry and slippery and reduces static charge so the record is less likely to attract dust.
There is a lot of experts that claim that vinyl records do not have plasticizers that can be extracted by alcohol and so it is safe to use it on records. I play it safe and use cleaners that are either free of alcohol or use low concentration alcohol.
