How to Use TSP

Using Trisodium Phosphate (TSP) requires careful consideration of its properties and safety measures. Here’s a general guide on how to use TSP effectively

Materials Needed

  • TSP (either in powder or pre-mixed solution form)
  • Protective gear (gloves, eye protection)
  • Clean water
  • Sponge or scrub brush
  • Bucket
  • Drop cloths or plastic sheeting (for protection)

Step-by-Step Guide

  • 1. Safety First; Put on protective gear, including gloves and eye protection, to avoid skin contact and eye irritation.
  • 2. Dilution; If you are using TSP in powder form, follow the manufacturer’s instructions for dilution. Typically, a common ratio is 1/2 cup of TSP per gallon of water. For pre-mixed solutions, follow the product’s specific guidelines.
  • 3. Surface Preparation; Lay down drop cloths or plastic sheeting to protect surrounding areas from splashes or drips.
  • 4. Testing; Before applying TSP to the entire surface, test a small, inconspicuous area to ensure compatibility and to check for any adverse reactions.
  • 5. Application; Apply the TSP solution to the surface using a sponge or scrub brush. Work in sections to ensure thorough coverage.
  • 6. Scrubbing; Use the scrub brush to agitate the TSP on the surface, paying extra attention to areas with heavy dirt, grease, or stains.
  • 7. Dwell Time; Allow the TSP solution to dwell on the surface for the recommended time, usually 10-15 minutes. This allows the TSP to break down and lift contaminants.
  • 8. Rinse; Rinse the surface thoroughly with clean water to remove the TSP residue. Use a sponge or cloth for wiping down surfaces.
  • 9. Neutralization (if applicable); If using TSP in preparation for painting, it may be necessary to neutralize the surface to ensure proper paint adhesion. Follow the TSP manufacturer’s recommendations for neutralization.
  • 10. Final Inspection; Inspect the cleaned surface to ensure that all contaminants, residues, and TSP have been thoroughly removed.
  • 11. Dispose of TSP Solution; Dispose of the used TSP solution according to local regulations. Only pour it down drains with proper dilution or treatment.


  • Work in well-ventilated areas to minimize inhalation exposure.
  • Follow safety guidelines and precautions provided by the TSP manufacturer.
  • Avoid mixing TSP with other cleaning products, as this may result in hazardous reactions.

Important Instruction

Always read and follow the specific instructions provided by the manufacturer of the TSP product you are using. Different formulations may have varying dilution ratios and application guidelines. Additionally, be aware of any local regulations regarding the use and disposal of TSP.

If using TSP in preparation for painting, follow up the cleaning process with neutralization as the manufacturer recommends to ensure proper paint adhesion.

what should you not use TSP on?

While Trisodium Phosphate (TSP) is a versatile cleaning agent, there are certain surfaces and materials where its use is not recommended due to potential damage. Here are some materials and situations where you should avoid using TSP:

  • Wood: TSP can be too harsh for wood surfaces, causing damage, discoloration, or deterioration of the finish. Avoid using TSP on wooden furniture, floors, or delicate woodwork.
  • Metal Surfaces: TSP may cause oxidation or corrosion on certain metals, especially aluminum and some alloys. Avoid using TSP on metal surfaces unless specified by the manufacturer.
  • Painted Surfaces: Be cautious when using TSP on painted surfaces, especially if the paint is old or in poor condition. TSP can strip paint, so it might not be suitable for surfaces you want to maintain.
  • Glass: TSP can leave a residue on glass surfaces, affecting transparency. Choose a glass-specific cleaner for windows and glass surfaces.
  • Certain Plastics: TSP may damage or discolor certain types of plastics. Check the plastic’s compatibility before using TSP, and consider using a milder cleaner for plastic surfaces.
  • Rubber: Avoid using TSP on rubber surfaces, such as gaskets or seals, as it can cause deterioration.
  • Lacquered Surfaces: TSP may damage lacquered surfaces. If you are unsure about compatibility, test a small, inconspicuous area first.
  • High-Gloss Surfaces: TSP can dull high-gloss finishes. Consider using a milder cleaner for surfaces with a glossy finish.
  • Certain Stone Surfaces: TSP may be too abrasive for certain natural stone surfaces, such as marble or limestone. Check with the manufacturer or perform a test in an inconspicuous area.
  • Electrical Appliances: Avoid using TSP on electrical appliances, especially those with sensitive components. TSP is not intended for use on electronic devices.
  • Certain Painted Walls: TSP can strip paint, so exercise caution on painted walls, especially if the paint is not in good condition. Test in a small area before applying to the entire surface.
