1 lb. Box TSP Heavy Duty Cleaner

This product makes nicotine just run off the ceilings & walls. Fantastic.

I used this to clean the grout on my bathroom ceramic tile floor. With just a light scrubbing with a scrub brush, the grout looks great. I definitely recommend this product.

So far so good after 2 weeks

The product probably got wet and ended up being one solid block rather than powder when I opened the box. I was still able to use it after chipping away portions to use.

I wanted to paint my vinyl siding but needed to clean it and remove a significant chalking issue. First I power washed with a dedicated siding cleaner and that didn't do it. Then I made a mixture of vinegar, water and dish soap and applied with a scrub brush, that took most of a day and didn't cut it, the chalking persisted. Then I ran across some saying TSP is good for this application. I purchased the TSP and made a mixture of 1/2 cup TSP, 1/2 cup bleach, 1 cup siding detergent to approx 2 gal or water and applied with a scrub brush. SUCCESS, the TSP did what nothing else could, removed the chalking from the siding so I can apply paint. Don't waste your time looking for other solutions, just throw on some dish gloves and eye protections and apply the TSP with a little ole fashioned elbow grease. Save yourself time, money and frustration trying "environmentally friendly" substitutes and products that don't work. Or, have your paint fail and redo it ever 3 years.

Did anyone know this is in most ceral? The box says harmfull if swallowed. This will be deleted soon. Please be aware and stay informed.

Exceptional quality—great cleaner.

I like to restore old furniture and I always use TSP to help prepare surfaces for painting. This comes in a powder form so make sure to read the label to get the proper mix ratio of water to TSP. Easy to use, simply get a bucket and mix the TSP properly with water, then use a sponge to wipe down whatever surfaces you are prepping. The cleaner does a good job of getting rid of grease and other junk you might have on your surface. Night and day diffference when you use TSP to prep your surfaces for painting!!
