What you should do is look for a deck cleaner specifically designed to be used on hardwoods. Messmer's makes a 2 step process that is typically used to bring back the color of the deck but should work on getting those water spots off. All the major online retailers carry it like Advantage, efloor, east teak, etc.

We have the exact same problem as Jeanaj. Brand new Ipe deck, cleaned it, applied Ipe Oil, had an overnight shower, and now the boards have "leopard spots" all over them. Can you please tell me what we should do? And will it work? Like Jeanaj, I feel sick about this.

Our best advice would be to wait till warmer dry weather. Will probably go away. If it does not seem to clear up after some time you may look at other options. Feel free to contact us with any questions.

same thing happened to me....twice! The first time, i did nothing and the spots do not go away. I live in SF and no rain was expected but fog came in and covered the deck I oiled the day before. The second time, I fixed it with 2 steps. 1) I swept the excess water off and used cloths to scrub the spots out. I was on my hands and knees for hours & it took a lot of elbow grease to blend them in, but it worked on 95% of the spots. Then when it dried & I could see what was left i used a tsp solution...step 2) 1/2 cup tsp to 2 gallons of water and buffed those boards with a scotch brite pad. Don't press too hard or leave the solution on too long or it will take all the oil off. But even if it does, you can reapply oil to those boards. good luck!

When applying Penofin stain, will overnight dew during the 12 hour drying time cause water spots?

I figured out water stains and pine resin removal!!! On the dry deck (previously olied), I used a dry microfiber cloth with a bit of hand sanitizer, just to have it moist. I wiped it over the boards with water stains, and they come off almost instantly!!! You need to reapply sanitizer every 3 sq ft or so, because it evaporates fast. On my deck, that was oiled 1 month ago, but had a kiddie pool on it and was a disaster, it left it flawless (including removing the pine resin with some elbow grease)! I thought it would require sanding and reapplying oil, because the wood seemed severely stained, some areas with large splotches of water, others with large drops, but this turned out not to be the case. An unwiped area on a plank looks no different than the wiped area in terms of ipe characteristics or sheen, though I think chemically it must remove a bit of oil from the very surface layer of the ipe, though again, this is not visible even in full sun and with my astute eye for details. I did reapply ipe oil, because I thought the water stains appeared because of the planks not being saturated enough with ipe oil. I read on some woodworking forums that until saturation is reached, ipe oil should be reapplied every season, and after that once every 1 or 2 years. I am new to this wood, so still figuring some things out, but at least water stains can now come out! Hope this post helps somebody else!
