Simply wipe with thin cloth slightly dampened and crumpled up with a light vinegar and water solution. Can add a couple of drops olive oil also, I do, and then buff with a soft clean cloth till shiny.
Before I get ahead of myself... hazy white stains are caused by moisture trapped between the finish on your table, and the wood itself. They are caused by water or condensation sitting directly on the wood. For example, condensation dripping off ice-cold water glasses, or hot food plates resting on the table.
In a bowl, combine one part toothpaste with two parts baking soda to create a thick paste. Apply some of the mixture to the white heat mark on your wood table and allow it to sit for a minute or two before wiping it from the surface. You may need to do this a few times in order for the stain to fully disappear.
To fix this, the surface needs to be scuffed and sanded first. Second, we recommend applying a sanding sealer to protect the top. Sanding sealer has a larger resin particle, so it will provide a better build for the next sanding step. Then finish with your topcoat.
Whether it's from a creative craft project or an extensive woodworking job, glue has knack for stubbornly sticking to floors, tables, shelves, furniture and every other kind of finished wood. Luckily, Goo Gone Original excels at breaking down the adhesive in glue and keeping your finished wood safe.
Mix equal parts vinegar and water (or olive oil) in a container. Dip a soft cloth into the vinegar and water solution and wring out any excess liquid. Gently rub the damp cloth over the water stain on the wood surface. Allow the solution to sit on the stain for a few minutes to penetrate the affected area.
These white cloudy marks were caused by placing hot dishes directly on the surface. It's been damaged like this for several years. A few are from Chinese food takeout containers and another was caused by pizza boxes. It seems the heat from the container scorches or somehow steams the finish.
This is almost certainly mold growth. Occasionally a white substance can occur due to efflorescence, but this only happens on masonry, concrete, etc. The widespread pattern of growth indicates high humidity throughout the room. This can be caused by poor ventilation, inadequate air conditioning or a flooding event.
You may make a spray with baking soda and water by combining the two in a spray bottle. Wet the moldy area with the solution and clean it with a gentle brush or cloth. Spray some of the baking soda and water solution on the powdery white mold on wood after you've cleaned it if you feel like it needs more work.
To remove a white spot from a wooden table, apply a small amount of mayonnaise or petroleum jelly to the spot, cover with a cloth, and leave it overnight. Gently buff the area with a clean, dry cloth. For stubborn spots, consider using a wood cleaner designed for this purpose.
Homemade Grout Haze Remover
Add three to four parts of distilled white vinegar to one part of cool water in a spray bottle. Mix but do not shake. When using vinegar to remove grout haze, it's usually necessary to use a non-scratching scrubbing pad to boost the removal process.
Mold is a type of fungus. It normally starts to grow in damp, warm environments when there are spores floating in the air.
Buff the surface lightly and evenly with No. 0000 steel wool dipped in linseed oil. Work with the grain of the wood, rubbing evenly on the entire surface, until the white haze disappears. Then wipe the wood clean with a soft cloth, apply two coats of hard furniture wax, and buff the surface to a shine.
"Mayonnaise works well to treat heat stains, or white stains on wood from fluid," says Poepping. Dip a microfiber cloth in a bit of mayonnaise. Dab the mayonnaise onto the stain, continuously wiping the spot clean as you work.
But she wasn't really correct if she said the furniture was ruined or that the only way to repair it is to refinish the piece. “All that white mark is,” said Gat Caperton, “is trapped moisture. The finish on your furniture is there to prevent the exchange of moisture from the air to the wood.
This usually happens when there's excessive humidity, the finish curing too fast, or coats are much too heavy. I would do a light sand to level it out. Maybe use a little heat from a heat gun to see if it will go away. Then recoat perhaps a little lighter on the coats.
Diluted vinegar can dissolve the finish that protects the wood and leave it looking cloudy, dull, or scratched. (The same goes for wood furniture.) Follow the manufacturer's cleaning recommendations or pick a cleaner that's made specifically for hardwood flooring.
The warm soapy water method
Using warm soapy water is a gentle and effective method to remove sticky residue from wood surfaces. Mix a few drops of mild dish soap with warm water to create a solution. Dampen a soft cloth with the mixture and gently rub the sticky area, applying light pressure.
Goof-Off comes in a metal container and has a stronger smell. It cuts through most every kind of goo and paint for fast easy removal. However, it can damage certain types of plastics. Goo-Gone is a bit more gentle and is my preferred choice for anything plastic.
