Hardwood Floors, Wood Furniture, and Other Wood Surfaces: Due to its acidic nature, vinegar can damage hardwood floor finishes, causing them to look dingy. Use either a cleaner specifically made for hardwood floors or a mix of soap and water.

Applying the white vinegar spray removes water spots, mineral deposits, and tree sap stains without damaging the clear coat.
The main difference between isopropyl alcohol and rubbing alcohol is the concentration. The concentration of isopropyl alcohol is 100%, while the concentration of rubbing alcohol is less because of the addition of water. Otherwise, the two liquids have similar properties.
Certain polyurethanes are more susceptible to swelling when submersed in alcohols. Polyether polyurethanes absorb alcohols quickly and significantly when compared to polycarbonate soft segment urethanes (Figure 6). This rapid absorption also results in swelling of the device both radially and longitudinally.
Alcohol will readily dissolve shellac, and it will slowly soften lacquer. Lacquer thinner will readily dissolve lacquer and will soften shellac. It will cause varnish to swell, crinkle and lift.
A mixture of mild dish soap and warm water is a commonly recommended solution for cleaning wooden furniture. The dish soap effectively cuts through grease and grime, while the warm water provides the necessary dilution. This solution is safe for most sealed or varnished wood finishes.
Caustic-based strippers
These are an alternative to solvents. They're most effective with thick layers of paint or varnish and work faster. The fumes aren't as strong so it's more suitable for indoor use.
Citristrip is a good alternative to Minwax If you're looking for a less toxic varnish stripper. Aside from Minwax, Citristrip was the best for removing finish.

Wood Pieces or Furniture
Whether you're cleaning a handmade family heirloom or brand new wood coffee table, rubbing alcohol should never be used to clean wood. The substance will strip away the color of the finish and eventually cause the wood to split.
The best solvents for removing varnish from wood include mineral spirits, denatured alcohol, and commercial varnish removers. These solvents effectively dissolve varnish, making it easier to remove. It's important to use these products in well-ventilated areas and follow safety precautions.
Safe Cleaning
It's important to dilute these substances properly. Too much vinegar can potentially dull the wood finish over time due to its acidity, while too much Dawn can leave a slippery residue. The ideal mixture typically involves a mild solution of diluted vinegar with just a few drops of Dawn.
In some cases, baking soda can cause discolouration on wood surfaces, especially if left to sit for too long. The alkaline nature of baking soda may react with certain types of wood or finishes, resulting in a faded or cloudy appearance.
White vinegar, also known as distilled vinegar or spirit vinegar, is made by fermenting grain alcohol (ethanol) which then turns into acetic acid. Water is then added to the vinegar, so white vinegar is made of five to ten percent acetic acid and ninety to ninety-five percent water.
