    Genuinely trying to be helpful here rather than a dick, but to clear a few things up:

    There's no real "strong", here. You have effectiveness (at dissolving the particular compounds you're trying to remove) and toxicity/flammability/other-badness to consider, and they're not necessarily related.

    I know you probably know that but for the benefit of anyone who doesn't it's an important distinction. I've had enough people tell me I'll poison myself using methylated spirits as a cleaner/antiseptic to last a lifetime :P

    As far as I know you can get them as nail polish remover (purity?). Be careful with any solvent, as virtually all of them are extremely flammable. Much more so than ethanol!

    If you want to avoid toluene you're going to have a hard time.
    Nail-polish will typically have fragrances added though a hypoallergenic variety might be ok. Personally I'd be getting a little tin of Diggers since last I checked they don't adulterate it.

    *EDIT* I've really gotta admire the kind of person who reads the below and thinks "This is something I want to make".

    As it appears that Becky, I and others have not quite gotten the point
    across, let me drive it home one more time.

    While you can usually tell a conversation among chemists has gotten lame when they start swapping lab accident stories, it is important that you **understand** that the risk of using this solution is nowhere near the reward.What Becky is writing about is 100% true. I saw it. It happened. It could just as easily happen to you. Read this and then ask whether a clean frit is worth this.I was the first one to get to scene of the above incident. We heard a sound like an M-80 (about a quarter stick of dynamite) from two labs away. We got there within about 5 seconds to find her on the floor halfway across the room surrounded by a large pool of blood.

    The filter flask that she was using turned to dust; we never found a fragment larger than about 2 mm even though it had been wrapped in heavy black electrical tape. The metal 3 prong clamp that held the flask sheared off at the point where it was clamped to the latticework in the hood. A row of glass cabinets along one wall were peppered with holes from the shrapnel.

    The lab had one of those 100 mm diameter glass drainpipes running vertically on the wall opposite the hood(about 8-10 m away) -- the pipe cracked in the middle ...we believe that it wasn't from shrapnel, but from the compression wave of the blast.The student was wearing rubber gloves, a thick sweater, a lab coat, an apron and safety glasses at the time of the explosion. The hood was down part way and saved her from catching most of it in the face. The arm holding the frit caught most of the damage -- the glove was completely flayed and her arm had several hundred small bits of glass in it as well as several fairly large lacerations.

    She had a wound about 20 mm in diameter just next to her jugular vein. At least one piece of glass went through her cheek. She (and everything else) was also covered with hydrogen peroxide and sulfuric acid; something that we didn't realize until much later because we had no way of knowing what had happened. I think the bleeding stopped more because she went into shock than from the pressure were were applying in two different places. She spent the next six hours having tiny bits of glass picked out of her arm, neck and face. I'm told that you continue to have those work their way out of your skin for the next several weeks after such an incident -- that you sweep your good hand across the arm and cut yourself on the glass sticking out of your own skin.

    This student had some nerve/tendon damage and lost a bit of the motion in one or two of her fingers; I can't recall if she had any hearing loss or not. All things considered, she got off pretty lucky. And yes, she did leave the program a short time after.

      As far as 700 word pedantic rants are concerned, I'm with Talk_Coffee, I simply don't have the time or inclination to wade through this sort of nonsense
      I read every single word... gives me something to laugh about while enjoying a fine, solvent free cuppa

        It's really not that hard unless it's hard on/off like a solenoid.
        I had to actually check what I do, as I'm on auto pilot....but yeh, that's exactly it. Then wipe down nozzle and purge.

        This thread is a real doozy. Like a dark rum party on a full moon at which 20% of the participants have been slipped a mickey.

            Well this is actually something tampit suggested in one of his earlier posts, not sure if it was in this thread or another.
            Like the others, I think this becomes a habit for most people after steaming milk but perhaps for newbies it isn't something they'd think to do.

            For any newbs reading this thread, I think it'd be a good learning curve, but perhaps not the best example of tolerance towards others....

              In fact that comment began the onslaught - now suddenly people are agreeing they withdraw the wand before the steam finishes. Go figure.

              I learned to do it in the Barista course I did last year - the instructor took pains to make sure we knew we should not leave the wand in the milk until it stops and explained it would save us lotsa work in cleaning the wand and tip.

              I've learned quite a lot from TampIt and he seems one of the most knowledgeable on CS about EM6910's - I've tried what he suggests and it works, so I tend to read what he says carefully. Better someone who knows the machine he is talking about - some others have sounded quite reasonable until you realise they mention boilers... of which the EM6910 has none.

                If your light has been blinking for low water try sticking a magnet there, i have posted on a different thread about this just now, but it seems that the low water indicator aswell as the beeping that happens when you turn the steam on somehow lowers the pump efficiency or thermoblock, i'm not sure what it does tbh but i'm guessing it's a safety mechanism, but try that, it worked for me, getting a proper whirlpool now after doing that.
