please read carefully - you may notice my proposition about "dwell time"

Time, thats your argument.

Enzyme stain removers work in minutes using cold water. Vanish for instance.

Vanish uses a peroxide - chemical releases oxygen to break bonds in the stain.
It is not an enzyme.

By the way, I am still interested in where you got your information on "new enzymes"

You appear to be under the impression I know what I'm talking about. I'm arguing with you because you implied you did. I was seeing if you did.

You may be right about vanish, but the enzyme stain remover I bought also makes similar claims.

Don't worry, I wouldn't make that assumption. I am right about Vanish :grin:

I do have a rough idea about what I talk about - about 15 years R&D in chemical industry, good qualification in analytical Chemistry, 30 years teaching science in secondary school (enzyme activity is taught from KS3).
My first job was carrying out testing of car exhaust catalysts - several years before they became a legal requirement in his country.

By the way - about 8 years of my industrial experience was working on PVC research, so I don't buy in to the idea of washing "mould release agent" from new records.
Vinyl for records wasn't my specialism, so treat my view with caution :grin: , but I don't think anything was sprayed on the the stamps to release the vinyl - imagine how much that would slow down the process.
I do seem to remember that stearates were added to the PVC during compounding (they lower melt temperature and viscosity and also help with mould release properties), but I don't think that they would wash off the surface of the vinyl with a few wipes of a wet brush.

So this becomes an argument over time.

I have a ultrasonic bath and a vinyl rotator. It cleans 5 lps for 15 minutes at 35 degrees . I postulate that would be sufficient.

I like science - smear some butter or margarine (if vegetarian) on your fingers. handle a record to leave finger prints and try different dwell times.
I think that the prints will still be visible after 15 minutes at 35, but give it a go.

Thank you guydarryl for your contribution which has brought interest to this thread and I’ve learnt quite a lot from you.

My personal experience of enzyme cleaners is with L’art du Som. I found it basically ok using an Okki Nokki machine although in my view it did not give a complete clean. From what you say, maybe it was a time exposure thing, the job being done in a household temperature of 20c. I was not convinced the vacuuming process removed everything and maybe some residue was left behind. It certainly left a noisier surface than ‘The Right One’ which I moved onto. Also, L’art du Son is a concentrate which needs to be dissolved. Unused dissolved solution can be stored in the fridge, but after a few weeks, it starts to grow solids within the solution which are hard to shake out when it comes to be used again. Record cleaning, after all is an occasional practice rather than something regularly done.

I have cleaned relatively few records in my ultra-sonic cleaner and I’m still using the cleaning solution supplied with it. I believe, like ‘The Right One’, this is an IPA/distilled water based mix. For me it works better than L’art du Son with best results achieved by 15 minutes at 30 degrees in the USC followed by a good vacuum on the Okki Nokki. I have picked up on the suggestion (elseware) from Vinyl-ant of giving a record a rinse in distilled water prior to the vacuuming. He has found this beneficial although I’ve not yet personally tried it.

Until I am convinced otherwise, my inclination is to stick with the good old IPA/distilled water cleaning solutions which seem to work pretty well.

Thanks TroutFisher, very kind.

I think that the idea of using distilled water rinse prior to vacuuming is an excellent one; again I have no experience of washing vinyl (I have tried wood glue and it works well - although messy and nerve wracking :shock: ), but I would have thought that a thorough rinse with distilled would make drip drying and evaporation an option.
