Beside above, how long after washing walls with TSP can you paint?

Do you have to rinse walls after using TSP?
Standard TSP must be rinsed away with clean water. Depending on how dirty the surface is, several rinses may be necessary. It isn't as strong as the original TSP, but it is well-suited for lightly soiled surfaces and general-purpose cleaning. It requires no rinsing when mixed as directed.
