How it behaves in this recipe
Trisodium phosphate (TSP) is a powerful cleaning agent that's effective for removing grease, grime, and preparing surfaces for painting. However, it's being phased out due to environmental concerns.

Questions
5 questionsWhat is the best substitute for trisodium phosphate?
TSP-PF (phosphate-free TSP) is the closest substitute, with similar cleaning power and no phosphates. For general cleaning, Simple Green or Krud Kutter work well.
Can I use Simple Green instead of TSP?
Yes, Simple Green is an excellent TSP substitute for general cleaning. It's eco-friendly, biodegradable, and provides good degreasing power for most cleaning tasks.
What can I use instead of TSP for siding preparation?
For siding preparation, use TSP-PF or a cleaner made for siding. TSP-PF contains no phosphates and cleans nearly as well as TSP for this job; mix either one as its label directs.
Is TSP-PF as effective as regular TSP?
For most household cleaning and paint prep, TSP-PF does the job, though it is generally a little milder than regular TSP on heavy grease and glossy paint. It contains no phosphates, but it is still a strong alkaline cleaner: wear gloves and eye protection and mix it as the label directs.
Can I make my own TSP substitute?
For light cleaning only. Baking soda and white vinegar in water make a mild cleaner, but the vinegar is used up reacting with the baking soda, so what is left is a weak baking soda solution. It will not degrease or prepare a surface for paint the way TSP does; for those jobs, buy a cleaner sold as a TSP substitute.
