Buy it now, buy as much as you can afford.
Would RecommendFantastic cleaning product. The perfect Strong BASE detergent that chemically turns grease, etc. into water soluble gunk that just floats away down the drain. This is "the phosphate" that the wacko environmentalists have banned from laundry detergents. I use it alone to wash my hunting clothes because it removes the blood completely and leaves NO Perfumy stench and NO glowing fluorescent brighteners.
Did the job!
Would RecommendTSP in powder/dry format makes it much easier to adjust the strength. Great product

TSP
Would RecommendI love this stuff. Great cleaner and I'll never paint anything again unless I clean it with TSP first. Wear some rubber gloves, it will literally strip all the oil from your skin leaving your hands painfully dry.

Concrete cleanup
The best to remove oil and transmission fluid on concrete. Used liquid 16 oz to one gallon. Did twice plus scrubbing and rinse downs.
Cleaner prior to painting
Would RecommendI cannot believe the amount of filth on a household's walls builds up over time. This product does an excellent job removing dirt. I understand how and why this chemical works after my many college chemistry courses. This an INORGANIC product.

Mix with water and will last along time
Would RecommendWe use this to clean everything, get a 32oz spray bottle for Lowes, mix with water and spray away. Looks just like water but actually cleans with some effort. Just used it to clean my laundry tub that had 20 years of crud including paint, some scrubbing and looks brand new, also use it on our newly painted white cabinets, does the trick.

Needed for sheen removal of semi gloss paint.
Would RecommendNeeded this to remove the sheen from semi gloss paint as described above.The previous homeowner didn't prep the walls in the home we now own so this is just one of the steps needed to prep for painting. Have used this on gutters to clean the metal before painting and the paint held up for years.

Best Deck and Fence Cleaner
Would RecommendTSP and Bleach is the best deck and fence cleaner. A must if you are going to stain/seal a fence/deck that has mildew or staining. You mix it per the package recommendations with Water and Bleach. Be sure to use plain bleach (Sodium Hypochlorite) not the deck cleaner variety which also includes Sodium Hydroxide. This is a very corrosive mixture, so adequate skin and eye protection should be worn at all times! Wear old clothes, this will bleach your clothes and anything the spray contacts. I've...
