I would think that TSP might remove any remaining luster. Perhaps a mopping with warm water and white vinegar could do the trick???

I would have aluminum oxide powder mixed into the clearcoat.

Thanks all. I cleaned twice w 1 part each white vinegar, alcohol and water with just a touch of blue Dawn using a micro-fiber mop. Then again w Bruno. Worked well enough - no need to replace.

Trickyputt, please tell me more about adding aluminum oxide powder to clearcoat. Is that something I can do now and what would be the result/purpose?

I would ignore that advice. If you want/need something to add sheen and a wear layer, I would recommend Bona Refresher (NOT Bona Polish). Aluminum oxide is a polyurethane additive that makes the finish more durable, mainly used in factory finished floors. There is a product with it that can be applied on site but it's probably overkill for your application. I assume the OTC product has a formulation that keeps the powder in suspension. Adding it DIY to a finish sounds like a recipe for disaster. It would have to be held in suspension to ensure uniform coverage.

Laminate cannot have "finish" applied to it!!! It is a photograph sitting on fibre board. That's it. It is not wood. It is a photo. If you add a "finish" (the aluminum oxide comment is about FINISH = can't be done with laminate/photographs) you will soak the paper/photo/fibre board and the whole thing will warp before it dries.

If you achieved a nice appearance after a good clean, then that's a great result. It is a photograph. You have, essentially, cleaned the "glass" of the picture frame.

People are getting confused because of the wording "wood laminate". They see "wood" and thing "real". In fact, the LAMINATE is the important part of the statement. I suggest you ignore the advice for "wood finishes". You can't use any of it. You can use a polish...but that is H3LL in a bottle.

Good luck.

The OP wrote "old wood laminate" so I assume he has engineered wood flooring, but I should have stated so.

@Johnson Flooring Co...no worries. I've seen this wording so often from homeowners because that's how their house was listed for sale "Newly Installed Wood laminate floors throughout!" - like it is a high-end selling feature. The "wood" is what buyers see, "laminate" is the reality. I wasn't coming down on you. I just wanted to make sure the OP realized that "laminate" doesn't take finish.

TTFN.

Got it. Understand the difference between wood and laminate.

.89 flooring isn't worth the effort of attempting anything on it but that scrub. And hope you didn't use so much liquid that you damaged the MDF core. Because it's completely ruined then. Laminate hates liquids.
