    Hi we had a logburner installed seated on slate but the plasterer dropped his plaster splats over it. I'm panicking as it won't scrub clean. I've tried a recommended mix of vinegar, bicarb and lemon juice paste to soak for 20mins. Nothing.
    Help!! Any ideas on how to clean the slate would be amazing.

    Would never use lemon,vinegar on slate, hot water & a few spots of washing up liquid, sponge it, or use rag,nail brush,might need to done several times,should remove it.

    When you have slate nice & clean, then you want to seal it witrh some slate sealer.

    I tried that first then read up on Google about the vinegar combi. It just seems so ingrained now in places

    If you have a bit of slate left over from your project, try using a bit of brick acid on it. It should be fine, but does depend on how much lime there is in the slate.
    If it is indeed fine, then just use a bit of brick acid to remove the plaster.
    I had a lot of multifinish plaster spattered on my quarry tile floor and it cleaned off almost without any scrubbing effort, leaving the quarry tiles spotless and ready to a good quality sealant.

    That's great - thank you. I've found a product from Screwfix which I'm going to try today - so fingers crossed - if that doesn't work I will try the brick acid.
