I like Murphy's oil soap, but I know others around here are not keen on it.
A lot of floor products contain wax, which can actually dull a laminate floor. I found this site for information on how to remove the wax (if that's your problem). http://www.ehow.com/info_12164184_use-laminate-wood-floor-wax-buildup.html . The best cleaners I've ever used (laminate or wood floor) have been the ones found at Lumber Liquidators...their hardwood floor cleaner also works great on my dark porcelain tile without streaking or leaving a residue that shows footprints. They may also have some suggestions of what to do. Love those guys!
Laminate floors are comprised of many layers of material the top layer is an acrylic plastic. This top layer acts a lot like a sheet of plexiglass...when brand new it is clear and shinny but as it ages and wears it begins to have very vine scratches and abrasions. This wear dulls the finish...imagine rubbing a sheet of plexiglass with fine steel wool. With a real wood floor the surface finish can be touched up with more new finish of by the process of sanding and refinishing. These are options not available for a laminate.
I have never seen a laminate look decent enough after 2-3 years and consider it a "disposable floor" having worked on real wood floors that were 80 to 100 years old The "green" option is to go with real wood or tile...simply to reduce the quantity of material that would end up in a land fill over the lifetime of the home.
you may be able to restore some of the shine by using a floor "buff" machine and a hard wax type product. At least this would give you a more uniform look, part of your problem is the dull area stands out more because other areas are still shinny...if the whole floor had a uniform satin or brushed finish it would not look so bad....buffing could give you this look.
it is only dull in one spot and I think that' s because I used something too harsh.
Any help for that?
I agree with KMS, you'll have to treat the whole floor to get a uniform look.
You might write the manufacturer if you are hoping to just fix the dull area. They may have some product available for just this purpose.
I have had good luck with Holloway House's Quick Shine. I am with Leslie D you have to remove the build up first. Then I applied Quick Shine.
there's no build up..never been waxed! was told to not use wax on it
I will try the Holloway's. thanks, Carroll...
If you know the manufacture of the flooring, contact them. They do make several products that vary from one manufacture to another that can restore the finish on the floor. Will not be perfect, but will make it look better.
