    After my brew today there was a lot of trub stuck to the element of my grainfather. I scrubbed for ages and it's not coming off, the Grainfather cleaner is a load of garbage and barely works. Does anyone have any ideas on hwo to remove this?

    Thanks.

    Keep it wet.

    I give it a scrape when it's coming to boil and a couple of times during the boil. Once I've emptied the hops from the boiler I add some water and give it a scrub with a brush. After running the cleaner I find a final scrub with a non stick scourer gets it clean easily.

    I use one of those stainless steel mesh pan scrubbers in my Ace. Takes it off super easy whereas ordinary ones hardly touch it.

    I tried one of these but it's very stubborn and hardly budges.

    Leave to soak with some vinegar than scrub. Rinse well

    All the SVB's with concealed elements have the same problem, luckily I have grapefruit , lime oranges, and mandarins in my garden so cut one in half and rub over the scorching. Citric acid or vinegar as mentioned above will remove it. Please don't scour it, it will make it worse in the future.

    Scouring is not the answer as it will just make the surface area larger to burn on with all the scratches it creates. I will recommend once again as in my previous posts to reduce the mash and boil element temp to no more than 1900 as it is the higher temp of the element that burns the wort on. Also use vinegar and lemon juice as Foxy says should get rid of the crud. Believe you me the lower element temp will more or less sort the problem with the added bonus of extending the life of all bonded elements as that is what burns them out using at maximum

    Bar keepers friend might shift it. It removed the scorched wort from my cooker easily when nothing else would.

    I find the stainless mesh pads don't scratch the bottom of my boiler as you're rubbing stainless onto stainless and there's no sharp edges to make scratches anyway. Had much less trouble with gunk burning on since I started using them.

    I found that the burned sugar on the base came from the mash, early on in using the concealed element vessel twice the boil had slowed I emptied the kettle, cleaned the base and away it went. What I do now, is full wattage to strike temperature 1700 for mash 2000 for boil. I rarely use the step mash process but the adjustable wattage is invaluable.
    Even though you may not see scratches if they are there the sugar will settle in them and burn, a highly polished surface scratches easily even with nylon scourers.

    I recently made a beerworks part grain kit., which required a mash and boil of grains before adding to to the supplied concentrated wort. I thought I'd be clever and add the wort to my electric brew kettle - result, boil temp stuck at 50-odd degrees, when I finally admitted defeat, switched off and drained, element caked solid in burnt sugar.

    I did finally remove it and got my electric kettle working again by a repeated combination of ( tried all of these repeatedly for about a week):

    - bicarb of soda mixed into a thick past with water and added to the element with an old toothbrush; leave for 15 mins

    - add water to cover the element then boil

    - scrub with a wire scrubber

    - cover with vinegar solution and boil

    - keep scrubbing, with abrasives (wire brush to toothbrush work at different stages, plus every other scrubber I could find under the sink)

    - keep boiling between applications and scrubbing

    - KEEP APPLYING BICARB OF SODA PASTE

    - eventually, you will reach a blissful stage where the burnt sugar starts flaking off in chunks as you boil - just enough water to cover the element,; THIS WILL HAPPEN, EVENTUALLY (*). don't give up. these elements are designed for long life -they will take the punishment. (if your kit always cloggs up, that's a separate problem, but is this a known grainfather problem?)

    (* you will be left with a permanent brown stain on the element, a bit reminiscent of an ill-kept but well used bog bowl, but regard this as "patina" - pronounced - "pat in arr", not "pat-eeen-arr" as the current crop of real tv buy-a-piece-of-shite-and-flog-it-on merchants would have it)

    Thanks for all your advice everyone, got plenty to work with to attempt to remove the crud. Does anyone use oxy to clean their GF?
