    When using "One-Dip" someone told me he just dips the spring in the bottle, I told him I decant a small quantity
    into a very small jar and dip it in there , to keep the "One-Dip " clean.
    Not a earth shattering question either way just a best practice question.
    What do you do?

    put some in a small container, no use in contaminating the stuff at the price. Also, the stuff evaporates so quickly that leaving the container open causes more to be lost.

    I guess one benefit of putting the hairspring in the bottle and not leaving the cleaner to evaporate is that you don’t inhale as much. Use in well ventilated area. Tri- and tetrechloroethylene is nasty stuff.

    But yeah, as it’s a solvent you’ll just disperse the oils in it and it will coat everything you put in the bottle afterwards.

    I think most watch material houses carries it but honestly, I wouldn’t buy it. An ultrasonic cleaner will be much more efficient with much less dangerous chemicals than dipping in trichloroethylene will be.

    Several times I have encountered hairsprings that can't be cleaned with either Naphtha or running through the L&R Master with Zenith solutions. There's some gummy residue that leads to coils that stick and makes that hairspring unusable, at least for me. I'm curious whether "One-Dip" would have any effect on that stuff.

    I have also had a couple of hairsprings that clinged even after cleaning solution and ethanol. I also tried TRI but to no avail. What finally got them clean was acetone! I am by no means a chemist and can't explain why, but ethanol and sometimes combined with acetone (separate, not mixed) has gotten my hairsprings clean. I haven't had a need to bring out the TRI bottle for a long time.......
