Hello everyone, I'm new to this site and actually come here because I've got an issue that I have no clue what it is.

I have a large aquarium stand project that I had to put on hold. The stand is for a 112 gallon aquarium and is roughly about 4ft in length by 4ft high, by 2ft deep, so I've already got some money tied up in this, hopefully it's not wasted now. I skinned out the stand with cabinet grade half inch plywood. I used Minwax stain conditioner prior to staining, then applied Minwax stain. After that is when I had to put the project on hold. The stand is sitting on my back enclosed porch out of the elements, and has been there for a month or so. I've noticed that on every single edge of plywood, there is a cakey white powder the whole length of the edges.

I've used Minwax before in another stand project and never had this issue. However, the previous stand was sealed with polyurethane after staining, whereas this one hasn't yet. Also I did not use the wood conditioner on the previous stand.

Any help with this and advice would be greatly appreciated as I've already invested time and money into this.

Followed the directions to a T on both the conditioner and the stain. The wood is pine. I did have some issues with my inexperience in staining on my first project that caused some blotching, so I figured I'd go with Minwax's suggestion involving the conditioner.

Now that I think about it, the edges of the plywood were not rubbed with the conditioner... there was no point in it as they were all going to be hidden by moulding and trim, and I only used it on the outer surfaces.

Would applying the mineral spirits to the wood affect the stain that's already on there at all?

I would have to agree with you Gotspiccoli on the salt creep explanation, except the wood is new and hasn't been used on a stand previously.

It does however make me think something may have gotten into the wood possibly at the store. Hopefully it will clean off, and only shows up on the edges and not the facing sections of the wood.
