TSP (trisodium phosphate) was indeed a common cleaner used for removing nicotine stains from walls. However, due to environmental concerns and potential health risks associated with TSP, its usage has become less popular and, in some cases, restricted in certain regions.
In place of TSP, there are various effective alternatives available on the market that are designed specifically for cleaning and degreasing walls, including those stained with nicotine. When looking for a cleaner or degreaser to remove nicotine stains from walls, consider the following options:
Citrus-based cleaners: Look for cleaners that are derived from citrus fruits and contain natural solvents like d-limonene. These can be effective at breaking down nicotine stains and cutting through greasy residues.
Enzyme-based cleaners: Enzyme cleaners use biological molecules to break down organic stains and residues. They can be effective for removing nicotine stains and other organic substances.
Vinegar: White vinegar is a natural acid that can help cut through nicotine stains. Dilute it with water (usually a 1:1 ratio) and use it as a spray cleaner.
Oxygen bleach: Oxygen bleach, also known as oxygenated bleach or hydrogen peroxide-based bleach, can be effective for removing nicotine stains and is generally considered less harmful to the environment than chlorine bleach.
Commercial degreasers: Look for commercial degreasers that are labeled as safe for use on painted surfaces and walls. Read the product labels to ensure they are suitable for the task.
When using any cleaner or degreaser, it's essential to follow the manufacturer's instructions carefully. Always test the cleaner on a small, inconspicuous area of the wall first to ensure it doesn't cause any damage or discoloration.
Regardless of the cleaner you choose, always ensure proper ventilation when cleaning nicotine-stained walls, as the process may release airborne particles. Consider using gloves and protective eyewear while working with any cleaning solutions.
Please note that specific product recommendations can become outdated over time, as new products are introduced and existing ones may change their formulations.
