WOCA Denmark Tannin Spot Remover – Neutralizes Black Water Stains on Oak & Wood | Water-Based | Indoor/Outdoor Use | Ready-to-Use Spot Cleaner for Acid/Tannin Marks- 0.25L Spray

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.

I bought this to remove stains from my oak parquet floor. Followed the instructions but nothing. Stains remain, no change, very disappointed.

We are selling our house. Didn't want to sand the kitchen workshop and reoil it - just didn't have time for that or to deal with the mess.I did some research and purchased various products wood stain removal products.This one was amazing, did have to use steel wool. Some marks didn't come out fully but a lot less noticeable.To clean an oak kitchen worktop that hasn't been properly maintained for 5 years with lots of stains and coffee marks took about an hourReoiled the top last night, and doing another coat tonight.We are delighted, wish I took before and after shots.I felt so embarrassed by the state of the worktop - but was put off doing it a thought I would need to resand itThe steel wool did discolour the wood slightly (not the product) but once oiled, you can barely noticed it.We are surprised and happy, our kitchen now looks loved!

I didn’t think anything would get the black mark off my wood floor resulting from a leak, but applied this for an hour and it was basically gone! Amazing!

If you’re struggling with a wet wood stain, this is a godsend. We were quoted over £400 by a French polisher to remove a large water stain on our table, however this product did the job for a fraction of the price. A quick polish over afterwards with some white oil and all was fixed.

Does not work very costly

After reading reviews I had great hopes for this product, sadly it didn't work on the stain on my floor though, but that's not to say it won't work for others! Arrived quickly and well packaged.

Easy for use good for small water spots ,value for money
