Paint-stripping capabilities: So strong that it will peel old paint from a surface along with the stains, TSP is often used for cleaning surfaces in the course of preparation for painting, particularly for exteriors. It removes splintered or flaking leftover paint that may impede the bond of the new coat.
TSP or Trisodium Phosphate is a non-sudsing powdered cleaner formulated for heavy duty cleaning prior to painting. TSP is excellent for cleaning and removing heavy deposits of grease, grime, smoke, soot stains and chalked paint from walls, woodwork and floors.
Paint Remover: Most latex paints including milk paint, on furniture can be removed by scrubbing with a strong solution of TSP. After stripping any piece of wood it's always a good idea to wash well with TSP to remove the wax that is in most paint removers.
TSP will break down the gloss of oil-based paint and opens the pores of latex-based paint, creating a surface to which new paint can adhere. A little can go a long way - 2 Tablespoons per 1 gallon of water. Note: Do not take internally.
Always be sure to completely rinse TSP from the walls (and let the walls dry) before you paint. If you don't, the new paint won't adhere properly. Rinsing the solution with a clean, damp sponge should be all you need to end up with a beautiful paint job.
However, it is not recommended for wood cleaning because of staining properties, nor is it used on metal or glass due to damage and filmy residue, respectively. TSP was deemed harmful by the Environmental Protection Agency in 2011 and is listed as a “hazardous substance” under the agency's Clean Water Act.
Dawn: You can use the original blue Dawn dish detergent instead of TSP to cut through surface grease. Pressure-washing: This is another alternative to cleaning outside surfaces with TSP. With sufficient and well-calibrated water pressure, it is possible to clean tough areas with only the pressure of the water.
One final point about painted surfaces: TSP is ideal for preparing surfaces for a new coat of paint. However, it will also remove the shininess, or sheen, from glossy painted surfaces, so it's not a good idea to use it for general cleaning.
This phosphate-free product doesn't cut grease as well as traditional TSP, but it doesn't have the same negative environmental impact either. Simple Green is an environmentally safe alternative for TSP that is also not an irritant. It is a liquid cleaner that can clean an array of surfaces and material.
First, put some rubbing alcohol on a clean cloth or towel to get it damp. Rub the area gently but firmly until the paint has been removed. If any stubborn spots remain, add some additional rubbing alcohol and continue rubbing gently.
Normally the areas are sanded and otherwise prepared before they are washed with TSP.
TSP is not your, gee-the-walls-look-a-bit-dirty-but-I'm-not-going-to-paint wall wash. Trisodium Phosphate etches or chemically scratches the paint surface while it strips away the grease. If you're getting ready to apply a fresh coat of paint, this is pure win as it gives the new paint better adherence.
Fill a plastic bucket with 1 gallon of warm water. Add 1 tablespoon of TSP and mix. Wet a sponge with the solution from the bucket. Wipe one small section of your wall vigorously.
The most accessible way to dispose of TSP in the home would be to pour it down the toilet so it gets treated properly. This is even safe on septic systems. Never dispose of used degreasing rinsates like TSP into lakes, streams, storm drains, or open bodies of water.
Notes: Rinse well with fresh water to insure all the TSP is rinsed away. Otherwise, a salt-like residue will remain that can leave a hazy gray sheen on the logs. If stain is applied over the residue, the gray sheen will be locked beneath the finish. You will have to strip the finish in order to remove it.
Mixing vinegar and other products such as ammonia or TSP (Tri Sodium Phosphate) found in many abrasive cleaning products can be dangerous. Unless you know what you are doing use one product at a time (mixing only with water if label dictates to do so) in a small test area.
All phosphates, including trisodium phosphate (TSP) are excessively damaging to the environment, particularly lakes and rivers. More than 19 states and several counties in 15 other states limit the phosphorous content of household laundry products to 0.5% (this is assumed to be a virtual ban).
Recommended for cleaning walls, woodwork, ceilings, concrete, metal, vinyl and aluminum siding. A phosphate-free cleaner which requires no rinsing. The perfect preparation to any painting project.
Another widely used concrete cleaner is trisodium phosphate (TSP). It is alkaline, so it will not harm your concrete, but it is alkaline enough to cause skin irritation and even burns.
With WD-40 Multi Use Product, you can remove paint stains from your car without any complications and damage to the metallic paint on its body. Whether you are dealing with fresh wet paint or old and dry stains, WD-40 would get the job done with equal efficiency and minimum effort.
Oil-based paint, once dried, is a difficult paint finish to remove. A solvent must be used to dissolve the paint layer after layer. Scrubbing with paint thinner or mineral spirits is one way to do it and using a chemical paint stripper is another way.
