Warmed cleaning fluids

I think what Oildude is suggesting is that once the (unheated, or at most body temperature) enzymes have finished their work of breaking down the surface dirt, then the steam heating shouldn't matter anyway; that seems reasonable enough. Just don't heat up your entire bottle of record wash as that would likely destroy the enzyme-cleaning properties.
The process intrigues me enough to be interested in "trying this at home".

I asked Paul Frumkin this very question years ago when he was developing the Audio Intelligent enzyme solution. He did some research on it and told me essentially what others have posted here - it's not necessary and will break down the enzymes in the solution.

I do however, use steam following the enzyme soak. I let the enzyme solution work for about 5 minutes and then steam for about 3-4 revolutions onthe VPI before vacuuming off the fluids.

I follow it with a double rinse or the ultra-pure water and have never, ever, had better results.

The reason i was thinking warming the fluid might help cleaning is i have several 30 year old direct to disc lp's that i cannot remove what i think is mold release wax . I have cleaned them using AIVS fluids. Some of these have been cleaned 20 times using AIVS and steam. But when i play them i hear alot of pops. So i looked at the areas that made the pops under a 30x handheld microscope and i see a crystal like deposit . Multiple cleanings have removed some of it but some still remains. I have ordered up some Micro Care Premier cleaning fluid with the hope this will remove these deposits.
I wish i could some how get a picture of what i see under the microscope. Whatever this deposit is it leaves a white powder on the stylus. So i was just hoping maybe by heating the cleaning fluids that it might help to lift this deposit.

That sounds like an excellent example of why many of us keep several types of cleaners around. At least you know you can remove it because you have already. Now it is just a matter of finding the right cleaner.

I used to think about warming up the enzyme solution. But frankly I think it would need much more heat than has been talked about here to realize any difference, and that would probably be counter productive. IMO

Are you sure what you're seeing isn't paper? I've come across a handful of records over the years exactly like what you're describing that have "contaminated" vinyl with bits of cardboard and paper in the vinyl.

I can only assume that they were pressed during the oil-embargo 70's era when so many plants were recycling vinyl and labels, etc. got in the mix.
