Alternatives to TSP for Cleaning the Walls Before Painting
Before you paint, clean your wall properly to ensure a lasting paint job. (wall painting man image by timur1970 from

Painting walls is a fairly easy do-it-yourself project; however, preparation is necessary to ensure the paint job will last. Begin by vacuuming and washing the walls to remove dust, grease, nicotine, etc. All-purpose cleaners, such as TSP, are available; however, equally effective, less toxic products can be made at home. Soap, vinegar, baking soda, borax and washing soda are useful for this purpose. After cleaning, thoroughly rinse walls to ensure good paint adhesion.

Dish Washing Liquid

Combine 1 tsp borax with 2 tbsp white vinegar. Add 1 cup hot water, and stir to dissolve the borax. After the mixture cools, transfer to a 473ml. spray bottle, add ... cup dish washing liquid---not dishwasher detergent---or ¼ cup Castile soap. Fill the bottle with water.

Baking soda

An all-purpose cleaner is made by combining ¼ cup baking soda, ½ cup vinegar and ½ gallon water. One-half cup borax can be added; increase the water to 1 gallon.

A paste of baking soda and water can be rubbed on walls to remove stains.

White Distilled Vinegar

Loosen stickers by dabbing with vinegar. Apply vinegar to mould and mildew stains. Vinegar combined with an equal amount of borax and diluted with warm water will also remove mildew. Mix well to dissolve borax.

Lemon Juice

Undiluted freshly squeezed lemon juice is effective in removing mould and mildew.

Washing Soap

Combine ½ tsp washing soap with a dab of dish washing liquid and 2 cups hot water. Mix until washing soap is dissolved and clean walls.


Another good wall cleaner combines 56.7gr. borax, 1 tsp ammonia and ½ gallon warm water. Stir to dissolve borax.


Use large amounts of ammonia only in a very well-ventilated area. Start with one gallon of cool water and add 1 to 2 cups of ammonia. For very dirty walls combine ¼ cup baking soda, ½ cup white vinegar and 1 cup ammonia with 1 gallon of hot water. Do not use this mixture on glossy walls that will not be repainted as it may dull the finish. Always protect your skin and eyes, and avoid inhaling the fumes when using ammonia.


Cleaners can be mixed in buckets, and sponge mops used to wash the walls; replace solution as it becomes dirty. Store products in new 473ml spray bottles.


When storing, label mixtures making sure to list all ingredients. Always store in bottles that have not been used for other products. Regardless of whether cleaners are homemade or store-bought, do not allow chlorine beach, commercial oven cleaners, dishwasher detergent or toilet bowl cleaners to combine with ammonia, vinegar, lye or rust remover. Such combinations will create toxic gas fumes.

Keep all products out of the reach of children and pets. Test products on a small inconspicuous area of the wall prior to using.
