    I warned about this phenomenon here at AK over 10 years ago. Unless one has an item they want permanently stuck to shelf liner, it is best avoided.

    Same experience I had with the electrical cover and foam protector.

    The dent pullers did a good job, but were cumbersome, and more a pita than anything else.


    This solved that problem for me.

    Help everyone!
    I'm trying to go by weight rather than volume (since I have a $10 digital scale, and no cylinders or pipets).

    5% IPA 99% (50mL=39.3g, density 0.786 g/mL)
    0.5% Triton X-100 (5mL=5.3g, density 1.061 g/mL)
    0.05% quat (.5mL=.45g, density 0.9g/mL, but only 80% pure so 0.56g quat, the rest 0.12g is alcohol I think)
    EDTA (3.4mM=1g=1.1mL, density 0.9g/mL)
    94% deionized water (943.4mL=943.4g, density 1g/mL)

    Does the math work for 1-L of cleaning solution? Am I in the ballpark?

    This raises something I've been curious about... what do you all typically use to measure out these chemicals/solutions? There are references throughout about using pipettes ... and some folks mentioned throwing the pipette away after a single use.

    Are there other convenient yet accurate ways (without contaminating)?

    What about reuse? (Dishwasher or boiling with a good rinse? I assume dishwasher would leave residue...)

    Thanks!

    (And... YEA, I finally finished reading the whole thread!)

    Like doodahman said

    For me, it is a lot easier to put a 1-L container (pyrex) on a $10 digital scale (below), clean it with IPA, and just add ingredients.
    https://www.amazon.com/AMIR-Back-Li...pID=41QZcIegWFL&preST=_SY300_QL70_&dpSrc=srch

    Processing for making 1-L cleaning solution
    1. Pre-rinse 1-L glassware with IPA, boil deionized water
    2. Start with IPA (5% solution, 50ml, 39.3g) — TOTAL 39.3g
    3. add Triton X-100 (0.5% solution, 5ml, 5.3g) — TOTAL 44.6g
    4. add hot deionized water (94% solution, 943.4ml, 943.4g) — TOTAL 988.0g
    5. add Quat (0.05% solution, 0.5ml, 0.45g, 0.56g of 80% pure) — TOTAL 988.56g
    6. add EDTA (3.4mM, 1g) — TOTAL 989.56g

    I do this fresh, each time I want to sit down and clean a bunch of records.
    (Although I'm still not sure I have the volume->weights quite right. Any help there? Thanks!)

    I have a package of 100 disposable pipettes that I bought at Amazon real cheap

    Just stop by a pharmacy, talk to the pharmacist and tell them you're blending a record cleaning solution, and need something that will accurately measure very small dosage. They have disposable non-needle syringes they'll give you for free. Get a couple.

    You're welcome.

    What is a low-cost product to reduce static and does that leave any residue after a double rinse, and if it doesn't (leave a residue), how does it work at reducing static after being rinsed?

    Any product in your solution that has a polar quality will leave a molecular layer behind, this layer is not removable with a water rinse, and does not really qualify as a residue. It is just the way things work at that level. The molecular layer of the quat will put a different polarity on the record surface, resulting in your anti-static characteristic. I'm not a chemist, and my terminology may be a bit off, but the principle stands.

    Enjoy,
