Try distilled white vinegar applied with a soft, clean rag, but try it on a small inconspicuous area.
Distilled white vinegar was recommended to me by Sal Zaino, the owner of Zaino showcar products, when I needed to remove some water spots from my black auto.
You might have to use an actual car buffer, the rotating wheel with some speed and use a good amount of polish carefull not to burn the finish or if there is a clear coat. But basically by hand sounds like you will not have the pressure or speed to remove, I am no expert but it fixes pretty good swirls and scraps in a mercedes benz finish and since you already have a screwed up finish it can't hurt if you do it carefully not to damage.
Thanks for the vinegar tip. I tried it... but it did not work. I'm at a loss.
I don't have an answer, but if I had this problem, I would try contacting either the speaker manufacturer or a piano company such as Steinway and ask for suggestions. But I do know from experience that piano black finishes scratch very easily - even from light pressure - with the wrong cloth or cleaner. Hope this helps
Are the speakers new? or have they been recently refinished.
Was this the original finish? Contact the manufacturer .
Can you find what type of finish is it i.e. thermoplastic (nitrocellulose or acrylic) or urethane.
Is the finish hard enough if you pressure it with a fingernail does it get marked?
Do you know if this was on the speakers before you acquired them?
If thermoplastic you can carefully heat one of the spots with a hair drier to see if the mark disminishes. CAREFUL you can cause harm if overheat try in a not that visible spot like the speakers back near the floor side.
Possible options are 1- polish them off 2- refinish the speaker . your comments
Did any of the remedies tried make ANY improvement? Black finish is beautiful but a nightmare to keep from marks and superficial scratches. I have a black ebony piano and have had good luck with a good mildly abrasive car cleaner. It may be the bubble wrap etched into the finish for some reason.Was the original owner aware if these were on the finish before shipping?
This may be of no relevance, but...
My Verdier Platine TT is piano black, and when I had the armboard drilled, we used a paper towel wrapped around the armboard to protect it while we were using a vise and drill press.
Soon as we removed the armboard, we noticed that there were marks on the armboard corresponding to the small bumps on the paper towel. These could not be felt or polished out, but the next day they were all gone. It seems the piano finish as used on the Verdier table tends to absorb moisture from items contacting it, and given a chance to air dry, the moisture evaporated from the finish.
You might want to carefully try a hair drier on low heat to see if it has any effect.
Hope this is your problem.
You can try small amount of car "Bug and Tar" remover. If the suface have several coats of"clear" applied as the last coat (more than likely), then you should not worry about damaging the finish. It also have wax in it to enhance the lustre after rubbing.
I have wrapped my piano black Apogee speakers twice in plastic wrap in the past(when purchased used from audiogon member & house remodel) with no problems. The plastic does leave a temporary swirl like mark in a few spots but after a cleaning with Windex there look like new! I think the bubble wrap might have had some sort of residue on it that left the permanent marks on the speakers. What brand/model are they? VMPS RM40? Good luck!
STOP! Don't try anything else on your speakers. You have what are called "pack marks" in the trade and the only way to remove them is to buff them out. A buffing/polishing machine is best, but it can be done by hand. I'd start with 3M Imperial Microfinishing Compound-Liquid. If that doesn't get them out you'll have to step down to 3M Super Duty Rubbing Compound, but try not to go there. Finish with 3M Foam Polishing Pad Glaze. If at all possible have this done by a refinishing/restoration shop for the best results.
Bubble wrap is abrasive.It is a mongrel thing for marking like this. The same thing happened to a dining table I sent to the other side of the world.
You need to consult an auto spray painter.They might be able to buff the marks out with a cutting compound.Otherwise a respray is needed.
I had a similar problem and I used 3M Imperial Microfinishing glaze that contains no silicone or wax..
Part No. 05992
This is not always available but try to check this out with a car store.
It is a little bit pricey and if you cannot obtain it, and all others failed, let me know.. I may be able to give you a small amount..
Bug and tar remover takes out a lot of tough things I also have used auto rubbing compound to remove marks, again try in the back or bottom first.
I think the suggestion about a mild abrasive may be right. If these are indeed a piano black paint finish over veneer, then some car polish may be just the trick. I once owned a pair of Roman Audio Centurions with the Galaxy Cream finish and the manufacturer suggested car wax to maintain them. I would try a little on a rag in an unobtrusive area to see what the results might be.
Tekhifi-I don't mean to be sexist. But this is a job for women. Try one of those helpful hints or Dear Heloise columns.
Thanks Guys: All good suggestions, but they didn't work. The speakers are serveral years old, so it is a hard finish. I was told different types of wool are used on buffing wheels and I'm afraid in the wrong hands more damage can be done to the finish and/or drivers. I am reluctant to try a hair dryer in fear of baking the marks on. And lastly, I'm not sure this is women's work (LOL). Keep the suggestions coming, please.
Keep the suggestions coming, please.
Call the manufacturer. If that doesn't work, call the piano store. Automotive paint is different than furniture paint, so you'll need different products.
In somewhat similar but not exact situations, I have been able to remove residue or small marks with BRASSO. It is an extremely mild abrasive and the distilate helps in the cleaning. I believe it will work and as long as you do not apply too much pressure, it works as a fine polish for most everything including lacquer finishes, plastic, and of course metal. There is no downside unless you apply too much pressure at one time. Polish slowly and patiently. There is one downside. If the original finish is flat, using the BRASSO will polish it to gloss.
Just try Johnsons baby soap, smudge a spectacles cleaning cloth into a wet soap and lightly wash out the stains.
I don't have any experience with the particular problem you're having but assuming the finish is some sort of synthetic lacquer or similar you might try something like the Novus plastic polishes. It comes in three grades and can be used progressively. I've used it for years on plexiglass and acrylic on both boats and motorcycles.Novus polishes
I would return them to the seller, any furniture grade finish should be protected by a non-marring packaging, and unfortunately the speakers were not. If the seller did not disclose this nor did they inspect the speakers before selling, it should be their problem to handle. I would not mess with it any more as the seller will likely not accept them back if you degrade the finish in your attempts to fix it.
Any fine furniture store will tell you you never use reactive materials such as plastic on a gloss finish. Movers always use cloth pads and/or soft pile lined burlap to protect expensive furniture.
if you don't want to return the speakers, your only other choice is to re-finish them. Because I doubt the stains will go away. You can actually contact places that fix and re-finish pianos and ask them what they think.
There could have been some sort of reaction between the bubble wrap and th speaker finish that the stains you see now are below the paint
"And lastly, I'm not sure this is women's work (LOL). "
Not womens work. Womens knowledge. They supply the knowledge. You supply the elbow grease.
Give the low heat hair drier a shot...just for a minute or so. It can't be baked on any worse than it is already.
I own Wilson Sophia 2's. They come wrapped in a plastic peel-off coat. They warn you to not leave this plastic sheet coating on to long. Temp and humidity up and downs may be why the bubble imprints are there in the first place,thus,tough to remove. Also, maybe the bubble-wrap was "dirty" to some extent before hand?? I think these may have been wrapped longer than stated, before shipping? I too would be angry, and then some!!!!
I have no clue how the bubble wrap can leave permanent marks on the piano finish of the speakers. Since you have tried various methods without any degrees of success, I would stop trying. You won't know as you may do more harm than good. As some posters have suggested, it may be wise to contact a piano store that refurbishes/reconditions used pianos. They would have a better idea on how to solve your problem. Normally they would grind of visible scratches and respray using special paint. If you do not want all this hassle you might want to contact the seller.
Is this a Female Problem? Try Meguiers "Scratch-X" auto finish cleaner.
I use it on CDs to help clear away scuffing.
It is an extremely mild abrasive for $1,000,000. car finishes to remove swirl marks etc. I would use it on your speakers if they were mine.
The Scratch-X definitely will NOT mar the finish.
Make certain you use a very very clean cloth. New 100% Cotton diapers are the choice, but I use VIVA paper towels and for a paper towel they are the best for no-scratch rubbing.
The bubble wrap petrochemicals have reacted with the lacquer or the lacquer was not completely cured when it was wrapped (takes several weeks to cure and it must be able to breathe and bubble wrap could prevent the surface breathing)...a polishing tool may help...don't use abrasive ....simply buff buff buff buff gently using broad strokes over the entire surface (don't concentrate on the damaged point alone)...if that doesn't work then the damage has affected more than just the surface layers of the lacquer ....you need to get a pro piano restorer to look at it as you may need many new coats of lacquer...a lengthy job to repair unfortunately.
I'm intrigued by your Meguire's "Scratch X" suggestion. Have you tried this before on piano finished speakers? I do not have any diapers, but would MicroFiber cloth work? That's what I use on my car.
I just purchased a used Music Hall MMF-7 with black piano finish (came covered in bubble wrap).
While installing a new cartridge, I noticed the circles mentioned by Tekhifi.
They are small and not noticable without high intensity light.
This answers the riddle, however...
Just a note, normally the professional that refurbishes pianos would advise against a total repaint job since they wouldn't look good compared to original even though they have done a good job. In most cases they would try to grind off and polish the finish to get rid of visible scratches. A paint job is for very serious defects or damage. I sympathize with your situation. Let us know when you have overcome your predicament.
I have gloss piano speakers and use this product with great success http://www.meguiars.com/?pro-car-maintenance/Final-Inspection
