    we've all heard the stories of the MELTING BROWN BUMP-ONS OF DOOM; the one thing i have not seen in my e̶x̶h̶a̶u̶s̶t̶i̶v̶e̶ half-a$$ed research on the subject is how to clean them off the wall. Anyone have any tried and true methods for cleaning the brown goo off a painted wall? (asking for a friend...)

    I would think the easiest way would be to scrape that area clean of goo and paint as well and then sand that area smooth and repaint the whole wall.

    Yep, Framah and Larry are, sadly, right. I had this problem in my gallery and scraping the carp off and touching up the paint was the only answer. Then I lay awake wondering how many indignant customers would sue me but fortunately that didn't' happen.

    Yeah! I'm sure the acid in it would remove the goo!! (maybe) alien-covenant.jpg

    Blow-dryer? Acetone? (As long as it doesn't eat the paint).

    Shayla... I think you meant.. flame thrower and, yes I think it might effect the paint, a bit.

    I may have the dubious honor of being the first to report this phenomenon here on the Grumble. Here are removal instructions I posted in 1996, and which are still valid:

    I have made several house calls to remove drip marks. On regular painted walls, here is my technique:

    >Physically scrape off as much material as you can without harming the wall. The nice sharp mitred end of a chopped wood cap moulding (or a bevelled acrylic handheld windshield scraper) works pretty well for this. UPDATE: YOU CAN ALSO USE SOMETHING LIKE AN OLD CREDIT CARD OR HOTEL KEYCARD.
    >Gently scrub the remaining residue with a mild solution of dishwashing detergent (such as Dawn) and water using a clean white rag moistened (but not dripping) with solution.
    >That should get most if not all of it. If you must go farther, try a little isopropyl alcohol on a soft cloth, again very sparingly. In any case, don't rub so hard that you would mar the finish of the painted wall.
    >Bring a supply of clear or felt bumpers with you, and replace any other older brown ones on other pictures in the house.

    When someone first calls with the problem, offer to look at it yourself, and tell them NOT to try to clean the wall using Formula 409 or any other commercial cleaners. That will only make a worse mess, as the cleaner itself will stain the paint.

    :mad: Rick

    Follow-up: You also want to caution the customer not to let any sticky residue that may be on the frame or backing get on other surfaces.
    I've been using the 5/8" felt bumpers from LJ ever since this whole issue came about, and like them better because they do not detriorate, PLUS, they stay put on the dust cover because of their aggressive adhesive. I have seen many instances of even non-melted Bumpons that have come loose and migrated out from their positions to stick out past the edge of the frame, or even crept around to the outside edge of the frame. Plus, I've found that even brand new Bumpons are fairly easy to knock off.

    Rick, how thick are those felt bumpers? And what do you use when you need something thicker?

    Especially where the art is somewhat proud of the back of the frame. I have sometimes used ones like these where needed. I keep them in various thicknesses.

    Air circulation behind the frame is important, so we use clear BumpOns, which provide about 3/16" of gap from the wall. We've not heard of the clear ones melting. Have you? We could not find felt bumpers that would retain 3/16" of loft. In my experience, they go flat.

    Yes, the BumpOns are easy to knock-off the dustcover if you just stick them on there. The problem is not the adhesive on the BumpOns, but the easily-shredded surface of the dustcover paper. Wipe off one and notice that the adhesive is no longer sticky, because it's covered with paper fibers disintegrated from the dustcover surface.

    So, we place a 1" square patch of Scotch Tape or Framers Tape under each BumpOn, which greatly increases the adhesive area on the dustcover paper. No more knock-offs. Or, for a neater appearance, use these clear tape dots, or something similar from an office supply store.
