10501 Wood Bleach, 12 oz,Black

It works pretty well but you will need to apply it multiple times, depending on how much lightening you want. Also, make absolutely sure you use this in a well ventilated area. This is a fairly potent acid and I started coughing just from the fumes as I was mixing it. I guess that's why it's so hard to open. Best option is to use a flat table knife or screwdriver and work your away carefully all around the lid.

Counter was damaged by soap sitting on it for a month or so in our vacation condo. Black spots didn’t go away even after sanding finish off, but this took care of it quickly and easily.

I actually ended up buying this locally because I didn't want to wait. I used it to bleach out some black marks on a midcentury danish dresser top and it worked perfectly. I applied it lightly, waited 10-15 minutes to wipe off excess and spray water on it to remove the bleach. Wiped down with dry rag and repeated the process. Probably could have done it a 3rd time, but I was happy with my result. After it dried completely overnight, I applied Daly's seafin teak oil--2 coats following their directions.

I purchased this product to remove water stains on an old gunstock. I was expecting fast significant results as per watched on You Tube.... I wasted a lot of time and effort applying, re-applying and re-applying with no apparent results. This product does not work at all even at high concentrations.

This didn’t work as well as I had hoped. I was attempting to lighten some drawer faces I had sanded to raw wood. They are quite ‘orange’ in their undertone and I wanted to make them lighter before sealing them. It helped a small amount and although I repeated the process 3 times, I just did not notice a huge difference. That being said, it was very easy to understand the directions and after reading about the process of bleaching wood, I realize it’s not a magic bullet. I think I might have chosen poorly, but the bag does say ‘wood bleach’ so I expected a little more. If you use this, DO follow the directions and use the safety goggles and heavy gloves. It makes a difference- especially if you drop the liquid once it’s mixed together. As for cleaning, it has been useful in getting some stains off our pool coping. It is also a good value and a quart goes a long way.
