    Hi,

    Apologies if this is the wrong place to post this.

    I recently moved into a flat and while I was cleaning, I found some a dirty, sticky substance underneath a bathroom sink (in the joint between the sink basin and the stand). As I just moved in, I have no idea what it is. I have uploaded some pictures I took of it at: https://imgur.com/a/ULTzdXz

    It looks horrible and was wondering if anybody here has any experience. Could it be a botched job at sealing the joint? Just accumulated dirt/gunk? Can I safely remove it? Should I seal the joint up?

    Any advice or help would be much appreciated. =)

    Looks like some horrible plumbing sealing gunk like plumbers mait or similar.

    Been use to bed basin onto pedestal, can clean it off,if you want to seal gap, use a sanitary silicone like Dow 785 or similar.

    This is the first time I am attempting such a job. Do you have advice on how to clean it off without damaging the basin/pedestal?

    It's a real nightmare to remove, use a plastic scraper,I find a old credit card useful,doesn't mark ceramic like metal can,but some use a stanley blade to scrap it off..
    Can use a lump of plumbers mait to remove itself,also a dry cloth to rub it off, & a lot of elbow grease is needed.

    WD40 might also work for removing,it's great for a lot of things.

    WD40 is oil though so that will need removing or the silicone wont grip.

    Time consuming but, credit card & dry cloth with elbow grease. OP wouldn't have to dig every last bit out.

    Meths will clean the WD away after using it to remove the silicone, I use meths on all surfaces before applying silicone to clean the surface.

    White spirit works on Plumbers Mait;)
    Always use it to clean up when I use Mait.

    White spirit will leave a residue.....so if it is used...remove it with meths to get a perfect clean surface.
    Also white spirit is highly poisonous and will absorb thru skin

    The tip about meth removing any residue is a good one, and meth leaves the surface clean with no residue.
