    Having to redo the caulk in a corner shower stall.

    The caulk has been on there for about 8 years. Starting to show signs of mold and mildew in some areas. (GE Silicone II)

    Easily pealed off where it is in contact with plastic/acrylic but the caulk that is on the metal framing is coming off in small bits and pieces. Pealing off maybe millimeters at a time.

    Found a local supplier of Lexel haven’t called yet to find out the cost.

    An abrasive pad (fine) soaked in mineral spirits has always worked well for me.

    Lexel is about $8 a tube, FYI. Home Depot carries it.

    I’m guessing the OMT/Fein with the duller CAULKING attachment would scratch?

    Against the acrylic surround, it probably would.

    I’d suggest a razor blade style scraper and a steady hand.

    Yes, a razor blade scraper to get the bulk and maybe what Chad mentions to get the residue.

    ThanX,
    I will give the abrasive pad and spirits a shot.

    I checked the Sashco website and they show only a few re-sellers in my area (Toronto, GTA, Ontario) and none of the box stores were listed.

    I did forget to mention that I do not want to scrape the paint off the metal frame. I did initially try an Exacto blade but noticed I was starting to remove the white paint.

    I did a bathroom recaulking last Winter that I posted here but I need to find the pics and where I posted it. Can’t recall if I just used a razor or the Bosch OMT. I could of swore that I did use the OMT with the caulking blade….

    Sometimes a moderately sharpened putty knife is safer to scrape with than a razor blade as it’s sharp enough to scrape but not so sharp it will shave off the finish. It’s less likely to dig in. I also round the corners a bit.

    After removing most of the material I use a white scotch brite pad with alcohol. Even a white pad can dull acrylic so remove as much as possible before you start. Sometimes a natural bristle scrub brush is safer.

    What about the super remover?

    http://www.homedepot.ca/product/paint-varnish-and-glue-remover-378-litre/915717

    Product only available in Quebec stores?? What;s up with that?

    I will give the putty knife a shot, I did find that a scotch bright pad was starting to dull the surface and the run off was white. Kinda like lightly sanding the finish. ARGH…

    @dirtywhiteboy,
    Tried that but it was scraping the paint finish off the metal frame.

    Razor knife for me too. I will have to give the abrasive pad soaked in mineral spirits a try some time. Thanks Chad.

    @58chev hey Frank, like on members have mentioned, I used a razor blade scraper type, slow and steady, can’t be rushed, after using a methanol to clean up properly. I will find the name of a product I also used in the past, it works great, I will post it up later today.

    I find razor blade too flexible, so I used a sharp wood chisel instead. But you have to be careful with the angle so you don’t gouge the surface.
