Would RecommendI used it to clean the cupboards (laminate) and ceiling rails after an incident which filled the room with cooking smoke. I worked pretty good at getting the black off and fast.

Did the job
Would RecommendEasy to use. Does the job of cleaning. I wore gloves as a precaution I bought the smaller product package because this was a test. I will buy the larger packaging for my larger project.

Perfect Prep for a Smooth Paint Job
Would RecommendI’m really impressed with how well this TSP Substitute worked. I used it to prep my walls before repainting, and it cut through old grime and kitchen residue way better than I expected. The surface felt clean, dull, and ready for primer with no streaks or leftover film. I also like that it’s phosphate‑free and doesn’t have a harsh chemical smell. It made the whole job easier and the paint went on beautifully. Definitely a product I’ll keep on hand.
