Savogran 10622 Trisodium Phosphate (TSP) 4.5lbs

I mix with equal parts of Muriatic acid to clean my pool filter. Works well.

This was my first purchase of TSP so I can't say whether this brand is especially good or bad compared to others.I wanted to try it as a laundry additive and wall wash specifically to remove synthetic fragrance. The tenant before us here stank up the washing machine with scented laundry stuff and it transferred onto our clothes & is proving very hard to remove! The TSP is definitely better than borax, baking soda, vinegar, or detergent, but perhaps not quite as good as ammonia. No matter what we try, it seems it takes a half dozen runs through the machine (with long soaks) to remove the vile chemicals. This same stinky tenant used some sort of scented candle or something in one of the rooms and we have it closed off until we figure out how to clean it up (I get very ill from certain ingredients in synthetic fragrance). We will someday soon be donning full PPE and scrubbing that room with TSP, after which I will update this review. We will also be trying it on the walls and benches in a little screened-in porch here that people used for smoking for many years. I have high hopes it can tackle that as it is the main claim to fame of TSP that it can remove smoke residue.Edit: OMG I'm sorry I forgot to add to this after I did the smoke abatement. STELLAR results!!! So we had a screened-in porch that had decades of smoke buildup on the walls, windowsills, wooden ceiling, vinyl flooring, and handmade rustic furniture. I was dreading all that scrubbing. TSP made it come off SO EASILY! Like a flippin miracle. So amazing. I put on a white suit and booties, taped the ankles together, also taped rubber gloves to the suit's wrists, and pulled the hood up around a full-face respirator. I hear TSP is a bit irritating to the skin but my big worry was all the nicotine & other poisons in the cigarette tar, especially as I've always been a nonsmoker so my body would be very jolted by a sudden big dose of nicotine. It was no joke- the dirty water came off incredibly brown like giant volumes of chew-tobacco spit hah!Sealed up well I took a bucket of warm water and rags for wiping, and a bucket of warm TSP water (about 1/4c for a couple gallons), with a sponge on a stick (I think it's designed for use in doing dishes) and a bristled scrubby brush for applying. I applied the TSP water generously over an area about 6'x 6', and then went back to where I started, and rubbed the area with more TSP water on the scrubby brush. In just ten min or so of sitting, it had dissolved the tar wonderfully and it came off well. The bristles were more useful for getting into crevices than needed for scouring. I didn't have to push hard or linger long. It worked perhaps a bit too well... the varnish came off a bit. But I think it had been carelessly applied, just a single layer. If you're planning to repaint after cleaning, this would actually be an advantage as the new paint would stick better to a corroded surface than a sleek one. The damaged varnish did not peel, it just disappeared- the fact that it's partially gone is not very noticeable until you look closely. No ugly flaking.Anyhoo, then I went across the same 6x6 area with the sponge-on-a-stick and the plain water. Changed the water then rinsed again with the clean rag. Dried with another clean rag. Then repeated on the next 6x6 chunk of the room. It took several long days but I was so proud when I finally got the last bit of it complete!This was done in the spring, and all summer, whether on baking hot days or soggy foggy rainy days, there was zero cigarette smell in that porch! The residues are truly totally gone! I can't believe it worked so great and it didn't take a long soak, or much scrubbing, or any tremendous heat... it was easy and simple (aside from gearing up in all that PPE)Oh, the picnic furniture I took out onto the lawn so when the rinsing stage came I just used the hose rather than fussing to wipe it all clean with rags. I rinsed the lawn pretty well afterward. There was no discoloration of the grass. So that was nice- I thought maybe it would either kill or overfertilize the grass.

Amazing stuff, but use with caution.

Cleaned my walls brilliantly before starting my painting project!

I use this for cleaning my pool's filter every so often, but my local building supply only offers TSP substitute which doesn't clean as well. I was glad to find this genuine trisodium phosphate.

My dishwasher stunk so bad. I tried switching detergents. I used Cascade and then switched to kirkland brand and I was cleaning it out regularly. Nothing was helping. After researching and trying various things I remembered my mom said dishwasher detergent used to be better but they took out the phosphates because it caused algae blooms that killed wildlife in river and lakes. After researching how and what phosphates do I decided to give this a try. (We have our own septic system not connected to a city system, we have to get it pumped every 3 years.) I figured with having our own closed system it would be safe to try. I used 1 tsp added to the detergent tray and the smell was noticeably less. After using this 3 times I can tell it's making a huge difference. The door of my machine is sparkling and no longer dingy with grease. (There was a pinkish coating all over the inside of the dishwasher) As for safety about using it on your dishes you'll have to look that up. They do add food grade TSP to some baked goods as a leavening agent. I don't know if I will use this for every wash or just weekly to keep my machine clean. But I am loving that this is working and I plan on using it in my washing machine also.

Got rid of the black armpit stains in my husband’s white undershirts. I think it is just magical and necessary for laundry to be clean.

I don't know how I have never heard of this stuff till now in my life. Used it to clean my trailer for paint prep. Be sure to scrub , First time i lightly scrubbed and primer and paint did not hold well
