WOCA Denmark Tannin Spot Remover - Removes Black Stains and Rings On Wood Furniture, Wood Cabinets, Wood Floors and Millwork - 9oz

Moved a neighbor's wooden table that had seen better days and was heavily stained to our pool area. (1st image) Did two applications, letting it sit for ours. (2nd image) Did everything come out? No. (3rd image) Can you still see the stains after restraining the wood? No!!! (4th image) Good product.

I have some stains on my hardwood floor. My wife applied this spray to them twice, but so far it hasn't done anything. I think I wasted my money. I don't understand how they can promise things that don't deliver results.

Worth the money! This product saved my hardwood floor. After a single treatment, the dark stain is already hardly noticeable. I applied liberally and let it sit overnight. Planning to do one more treatment to get the floor as good as new.

It works. I was able to eliminate 85% of the stain. The stain is still visible, but much better than it was before. The product is good, but don't expect the miracle.

I tried white vinegar on some black circles on a Walnut table top. I left it on overnight and it removed about 75% of the black marks. I then sanded the area removed the remainder of the marks. I then used the WOCA Denmark Tannin Spot remover on some other black marks and the results were about the same. Because of the high price of the WOCA Denmark Tannin Spot Remover I would just use plain white vinegar when removing tannin marks from furniture.

You need to be patient. This product does work, but it's not instant at all. You should expect to let this sit against the wood for a while, and it might require repeated applications to get the desired results, but remember that dark stain didn't happen instantly either. Clean the surface well, apply this product liberally, and wait as long as you can before wiping it up. The active ingredient needs to stay wet to work, so covering the area with cling film can be helpful to prolong the working time of each application. Expect to wipe up yellow slime afterwards, those are the dissolved tannins.

Doesn’t work at all I tried this 3 different times and the s is what it still looked like.

First photo shows, to the left, my first application to small area with the second application to rest of stain. You can see how well the first little patch worked. The last photo is the next day after a couple of applications the night before (I did wipe off after 60 minutes) I will do one more application but without getting up close with the camera the stain is gone, no one would ever notice it. The stain was water from an air conditioner.

Absoluut een aanrader alle donkere vlekken zijn weg binnen 30 min. was ons probleem opgelost.

Polecam na lekkie plamy.

Ich schreib selten Bewertungen, aber hier muss ich. Ich hatte auf meinem Parkett durch eine nasse Tüte, die über Nacht stand einen riesigen etwa 50 cm x 50 cm großen schwarzen Fleck. Übler, als alle Fotos, die ich hier bei den Rezessionen gefunden habe. Sah aus, wie ein Brandfleck. Leider hab ich keine Fotos gemacht. Das ist echt ein Wundermittel. Zwei mal 90 Minuten einwirken lassen und der Fleck ist nur noch ein Schatten! Hätte ich niemals gedacht. Ob es bei allen Flecken klappt, weiß ich nicht, aber ich kann nur jedem empfehlen es zu versuchen. TOP!

Ho un pavimento in rovere sbiancato trattato ad olio,questo prodotto toglie, come dichiarato, le macchie scure causate da caduta di acqua sul parquet non rimossa all'istante. Le elimina perfettamente senza lasciare aloni nella zona trattata per cui si può mettere il prodotto senza il timore. Ho provato ad utilizzarlo per macchie di natura diversa,non ha funzionato del tutto ma le ha schiarite. Molto soddisfatta!

My husband washed our engineered wood floor with a chrome/steel table on it. This left giant unsightly black marks as a chemical reaction took place between the metal and the wood. I got this spray having tried a lot of other "solutions" on the internet that did nothing other than strip the oil out of my engineered wood floor. For the record, I tried both bicarb and barkeeper's friend and they just left big white marks on the floor. Got this in despair, not really thinking it would work. Half an hour later the marks have all lifted. Amazing. And it was so easy to use and didn't even smell. I'm delighted. Wish I had just used this first as I now need to re-oil the floor because of the damage done by earlier treatments. 100% recommend.
