TSP (Trisodium Phosphate) is a heavy duty cleaner that removes grease oil, sooty dirt, and prepares painted surfaces for repainting or staining. Effective on decks and siding also. TSP removes dirt and grime.
This product is a highly effective cleaner that, when mixed with water or other cleaning agents, will clean nearly any wood surface including mildewed, grayed or sap-stained areas.
Mildewed Deck & Siding: Remove by washing with 1/4 cup of TSP dissolved in 3 gallons of warm water and add 1 quart bleach. Pre wet structure first and then apply from bottom to top of structure or side to side for a deck. Let the solution set for 10 to 15 minutes and rinse thoroughly, thoroughly. Wait at lease 2-3 days of drying before applying a stain. This way we won't be trapping moisture in with moisture!
This will revitalize your previous stained or bare wood surfaces.
