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.
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 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 Rs
OMG! The amount I have used cleaning bitumen and Denso tape off my hands for the last 40 years I'm a dead man walking!
The tip about meth removing any residue is a good one, and meth leaves the surface clean with no residue.
