Wood Bleach
I turned some wet apple into natural edge bowls. They turned out
great. BUT... After a few days they started to get some black mold spots. I used some wood bleach on them and it got rid of the mold spots and whitened up the sap wood. They looked great. BUT... Now they have been setting for about a week or so. I went out today to finish sand them and they all have turned pink. Mostly the sap wood. Now they don't look so great. This is the first time I ever used wood bleach. Is there something I could have done wrong? Is there a way to get rid of the pink color? Help!! Ted |

Ted Hi Ted I don't think you can reverse what you have done. So I would suggest you either live with it or sand or turn it off. The bleaching is almost always very shallow, but it takes a while sanding, if you can return it you would get it dome a lot quicker. Next time you have some mold just wipe it off with a dry rag, then get a little drier place for it, the mold stain from just a few days old does sand off easy Have fun and take care Leo Van Der Loo |

The pink is probably a combination of chemistry, because the sapwood does contain the chemicals which color the heartwood, and some leaching of the extractives in the heartwood along the borders. Only answer I have to the problem, and it's the same with cherry, walnut and the like, is to dry things more rapidly. Also helps with the mildew. Try blasting compressed air through the wood to kick out the maximum amount of unbound water, and you might shorten the time it takes to get below 18% moisture by a day or two. Mildew can make a lot of growth in two days. The two-part wood bleaches are your candidate, but if you get them in the heartwood, things can get splotchy. |

Wood Bleach
I sanded and sanded and sanded. It comes off with sanding. Not
perfectly white but it is pretty good. Thanks. Ted So I would suggest you either live with it or sand or turn it off. The bleaching is almost always very shallow, but it takes a while sanding, |

Wood Bleach
A lot of woods will do this, especially fruit woods. The sap wood is
white until exposed to air, then it goes red/orange/pink/yellow. I figure it is a kind of oxidation. Some woods get darker with age, some get lighter. Can't do much about it unless you put it into a vacuum with no UV light. You can sand it out, and it will still go pink again.

Welcome to the world of wood. robo hippy I hate to go off topic but..... Robo, you mentioned oxidation and I'm inclined to agree, but how would I promote oxidation. Here is the reason I'm curious. I picked up some osage orange from a ladies yard that had been cut for several weeks. Instead of being the typical yellow color, the cut ends of the logs were a beautiful red color. I had never turned osage, so imagine my surprise when I cut it open and found out the wood was actually yellow. I like the look of the wood as it is, but I'd like to see some of the red color that I saw when I picked the wood up. I know that bleach is an oxidizer, does anyone know if the red appeared in the osage because of oxidation, and if it did, would bleach bring out more of it? Hmmmmm..... sounds like an experiment could be coming on, but didn't want to repeat something that has already been done. THanks, JD |
