I used tongue and groove for my loft floor/main level ceiling. The main level is all sealed with Varathane floor sealer. I need to bleach the top floor before sealing. Seems like there are 2 deck brightener products, Sodium Hypochlorite and Oxalic Acid? I have no way to rinse the wood at this point. Is it ok to use one of these products without rinsing, or will it cause a longer term decay of the wood. Thanks. Ken

Rinsing would not really amount to much more than using a vinegar/water wash down with a sponge or rag a couple times. You do not really have to rinse by spraying. Then allow sufficent time to dry. I would be worried about leaving the residue and trying to get a finish (stain/poly) on top.
Oxalic acid is my first choice, it removes mettalic stains better and doesn't "bleach out" the wood as bad.
