Hardwood floors are highly desirable for most homeowners, but they come with their share of challenges when it comes to cleaning, maintenance, and repairs. After a few months or years of heavy use from kids playing with toys and chairs being shuffled around, it may be time for some DIY fixes.Hiding scratches: If you’ve got a good eye for matching colors, you can actually use crayons or markers or purchase wax sticks from the hardware store to fill-in scratches. Try to match the stain color on your floors, but don’t worry if it’s a little off. If the color is close, once the scratch is filled, it’ll look like a variation in the wood grain.Polishing floors: You can make a polish solution for your floors from household ingredients. Mix olive oil and vinegar in equal parts, pour it directly into scratches, and then wipe it off after 24 hours. It may take several applications, but this homemade polish will fill and cover most scratches.Clever decor: It’s not a long-term solution, but sometimes the most painless way to fix scratches in your floors is to cover them with a rug or furniture arrangement.Spot sanding: For deeper scratches, you’ll need to spot sand with fine steel wool or sandpaper, use wood filler, and stain and seal the repaired area.
