Could that also get the white streaks out that are there right now?

There have been several threads on cleaning wood floors with many differing opinions. I've linked to a few below. I suggest as you read through them that you specifically note the advice given by flooring experts:

We have engineered America walnut and were td by the contractor to use a little vinegar and warm water mix, in a spray bottle! I spray a small area then use Rubbermaid revel micro fiber mop to mop up! I do this once every other week and vaccum every other day !

There are "streaks" (because of oil/grease/cleaner) and then there are scratches that are white. Which one's do you have? Some finishes, when the scratch they turn white. These scratches are almost impossible to deal with (read about aluminum oxide finishes).

If your are streaks, then a decent (purchased from the company that sold you the engineered hardwood. This will be "pH Neutral Hardwood floor cleaner"...or some such wording.

To get rid of the "white streaks" please tell us if these are scratches or are they residue from "something".

They appear to be streaks. The cleaners used Mop n Glo. I had immediately realized that it wasn't the right thing to use. I'm looking to get rid of the streaks. At the same time looking for the right cleaner. I have Bruce engg wooden floor.

NOOOOO! Another floor ruined by Mop n Glo! Not ruined - yet. It can be saved....but you have a LOT of work a head of you. You are going to do a "hands and knees" floor stripping (ammonia + hot water) using strong sponges (not abrasive) and working 2ft x 2ft areas until the entire floor is chemically/mechanically stripped of the Mop n Glo.

To find out if this is going to "work", try a small patch as a test run. Find some glass cleaner WITH AMMONIA - Windex is the brand name...but any glass cleaner with ammonia will do the trick. In an "out of the way" area of your floor, you are going to spray (2-3 squirts) of windex onto a small patch of floor (1ft x 1ft). Let sit 1-2 minutes. With a sponge dipped and wrung out (hottest water you can handle), you are then going to rub off the Mop n Glo in that small patch. You will find that the mop n glo will turn a bit goopy - perfect! This means you are breaking down the bonds! Wipe up as much as you can with the sponge.

You will use another squirt of glass cleaner and then quickly wipe up the left over with paper towels. At the bottom of this 1ft x 1ft area, you should find your original floor. Good. Now you know what is going to work.

Now you know it will work, go out and purchase household ammonia and an "All purpose cleaner" NO BLEACH! Lysol works just fine...NO BLEACH! Here is your mixture:

1/4 cup All Purpose Cleaner
1 cup Household Ammonia
1/2 Gallon warm/hot water

This mixture will save you having to purchase oodles of Windex. Now use the same technique as above, clean the rest of your floor. A few hundred square feet could be an all day affair, so be prepared.

Ask your cleaners if they have an offer for you because they are using a product that is GUARANTEED to cause damage to most floor surfaces. Here is the link I found this on:

Cancork Floor Inc, Thank you very much for all the advice. I had a chance to speak with Bruce Company yest, they advice me to do the same thing, but the product they suggested was "Low/No odor mineral spirits". Did you hear about this before?

Mineral spirits are great for clean up of paint, etc. If Bruce states that you can use mineral spirits, that means you have a substantial finish on that floor. I would start with the mineral spirits (it is the "nastier" of the two cleaning options) and if it isn't successful move to the ammonia option.

Mop n Glo has stated that the ammonia mix is the way to clean up their product. Again, start with a small patch and see if it works. The mineral spirits work on the Bruce flooring product....but it may not work on the Mop n Glo.

Got it. I will go get Windex right away. The one thing I'd like to know is after doing all this, how would I know that I got rid of all the mop and glo. The cleaners used it twice so far, once last month and the next this month. If the streaks are gone and floor is less sticky, is that a good indication it has gone away! Thanks, Cancork Floor!

Thank you again! I will be doing this over the weekend and will update soon after.

I've had this same experience and am so sorry I put in dark engineered hardwoods. They look good for an hour or two then start to look dull and show every foot step. I'm wondering if anyone knows if I can put a polyurethane or other finish on them to make cleaning more manageable?

How shiny are your floors? What do you use to clean them with? Dark floors with a high shine/gloss level show most everything. "Dull" after a few hours means the product you are using is affecting the finish. Before you refinish your wood, we have to establish what type of product you are using the clean/mop the floors with. We discovered the "streaks" and dulling of this person's flooring = Mop n Glo = NOT ALLOWED on hardwoods. What have you been using? It may be the problem.

I had used mop and glo in the past but have had two all day sessions on my hands and knees to remove the film and flakey white residue that product left behind. I've been cleaning with vinegar water since then. The original finish on the floor is matte. Thanks for your help.

I'm listening to this topic. I'm finding it very informative bc we have engineered wood floors also. Thank you kavithabanda for posting your question

A matte finish will remain "dull"...that's why it is called "matte". I've been reading several posts where many clients have complained the "matte" finish means that foot prints show up all the time. There is no way to make a matte finish "shiny" - except to refinish. A satin finish is about as low gloss as I would go. Satin normally has a very slight sheen but not enough to be "mirror like". It is very forgiving with dirt/dust/foot prints.

I can't confirm that "matte" shows the oil of foot prints, but I've read enough posts with this comment that it sounds like there is a pattern with matte finish and foot prints/oil smudges from skin.
