    Default Saw blade cleaner

    I am looking for a something to clean saw blades but I dont want to buy CMT stuff (not for any particular reason other than being determined to find something more generic at a hardware shop).

    I have tried turps, methylated spirits, kerosene, sugar soap. None of these work well.

    I read that simple green works well but is not good for bond between steel/blade teeth.

    I saw a youtube video of an auto degreaser called 'super clean' which cant be bought here. Has anyone tried another degreaser from bunnings/auto store which works well? By works well I mean a quick soak and it wipes off

    What is your method? do you mix up a batch or sprinkle it on whilst it sits in a tub or water

    I mix the CS with warm water. Be careful because it will boil up and shoot out at you if the waters to hot . Just lay the blade in a tray of strong soloution and it will start working . A rub with steel wool is good . It eats the sappy gum build up easy . Chisel mortiser bits really suffer from a build up of that . I soak them in for a while with no scrubbing and it all runs off.

    How did you do it - wipe on rub of? If so I am not surprised they did not work.
    I found the leaving the blade to soak overnight works to loosen hardened sap.
    Even coffee grounds soaked in hot water works as caffeine is a fair solvent for sap.
    If you want to use something faster and don't want to use something as nasty as caustic soda then non-caustic oven cleaner also works.
    Suspend blade over a tray of some sort and spray foam on both sides - leave for a few minutes and repeat.

    With all of that stuff I used toothbrush/brass brush after a soak. Still too much work for me lol

    Out of curiosity - has any one tried using a pressure washer? A Karcher or similar.

    I don't see why Simple Green is bad for the brazing between blade disk and tooth.

    I use Simple Green and an old tooth brush. A little bit of work and 15 minutes of work. Rinse in hot water as you can get from the tap. Dry with an old towel.

    A bit of advice. Don't use a new towel as SWMBO won't let you forget it. Also, don't try putting the blade in the dishwasher.

    I actually read that caustic soda is bad for the brazing too. But then I read that it would like a very long time in contact for it to actually damage it. I suppose the same for simple green.

    How well does simple green work? Is it literally soak and wipe off?

    As Rich said you do need to use an old toothbrush, but you don't need to get too physical with it. Only needs to soak for 10 to 15 minutes, in fact if you leave it soaking too long you'll dissolve any writing on the blade. It works great.

    Using a tooth brush and hot water sounds about as simple as it gets and it can be tried for no money, if it doesn't work move on to another method.

    I use oven cleaner, which works very well.

    Spray on, leave, hose off. Spotless.

    Wot Arron said. I used oven cleaner to remove cooked on gunk from my bandsaw blades. Worked a treat.

    I do the blades for the Woodcraft Guild of the ACT, which is quite a few blades. About 1 per week.
    I use the cheapest oven cleaner from woolworths on our stock of 10" & 12" tablesaw blades and our 12" miter saw blades. I put one in a plastic garbage_bin lid, (wearing rubber gloves) spray both sides , leave for 30 minutes, then hose them off, dry with clean rag, then WD40 to get rid of any leftover water, then wipe again with rag and put into ready storage

    I use Coles double strength vinegar on our bandsaw blades, which I like to clean before sharpening.
    Immerse the blade in dbl_Str white vinegar in the rubbish bin lid
    leave for 30-60min
    extract & run under tap. Dry with rag. Spray with WD40 to displace any remaining water. wipe with rag

    If you want to re-use the vinegar, filter it through a coffee filter paper back into the jug.

    If I want to do a quickie clean of a blade on the bandsaw (if one of the members has been cutting green wood or a heavy tannin wood, I use a circular wire brush chucked in a cordless drill on the fastest setting. I rotate the brush in the same direction as the teeth, clean both sides of the blade ten clean the tire with a scotchbrite and metho. After cleaning the tyre I wipe it with parrafin oil to stop the metho from drying out the tire.
