Powdered TSP (4.5lb)

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.

Worked great in the roof shingle stains. I mix a cup of TSP with a couple cups of bleach and fill up a 2 gallon sprayer. Then wet down the shingles with a hose and spray the TSP/Bleach solution on the shingles generously. Let it sit for a bit and rinse off. Stains gone! Great product, great price, great delivery.

Not being able to find true TSP in my local big box stores, it was nice to find on Amazon. Product was somewhat caked when I opened the package, but those clumps easily dissolved in water. Great cleaning power.

TSP is the quality go to for cleaning before painting and other projects. TSP is known for its cleaning power, easy to use, with no harsh smells . I was very pleased to find it in a 4.5 lb resealable bag at a very reasonable price.

This is REAL TSP, not the fake, ineffective "TSP Substitute" that is all too common these days. So the product itself is excellent. However, because this is a heavy powder in a box (much like detergent might be), it needs to be packaged for shipment in an outer box, preferably with padding or a tight fit so it will survive normal handling during shipping. I've received two of the three of these that I ordered, and they were both simply placed into shipping bags, and of course, the boxes arrived broken open, with the product spilling out. I've had to repackage the remaining powder since the original boxes arrive fairly well destroyed. So the product itself is excellent. But the boxes need more substantial packaging prior to shipment. But I do sympathize with how expensive it must be to properly package and ship such a relatively inexpensive and heavy product, too. And I was happy just to find a source for real TSP. TSP is a very effective grease cutter, but has been hard to find due to environmental regulations which are designed to limit phosphate pollution of waterways.

The real deal, genuine trisodiumphosphate! The “substitute “ garbage sold at the local stores does not work and therefore doesn’t compare. Came in a sealed marked bag rather than the box pictured, but I can’t complain at all about that. It had not absorbed any moisture and become a solid unusable block like others have mentioned. Still completely granular and usable!!! Easily removed smoke stains from walls and ceiling with minimal effort. Very easy to use and was completely soluble in warm water. Did not have any harsh smells at all!

Buen producto de apoyo para la limpieza en general. Fantástico para la remoción de grasa y manchas muy-muy difíciles. Recomiendo sea usado con discreción; contienen fosfatos.

Great cleaning product, but have to take care on what surfaces you can or can’t use it. Must read instructions. Did the job I needed it to do. Comes in big package so I have quite a bit left for next time.
