Q: Will it freeze

a month ago
1 Answer
  • A: Howdy neighbor! No, Klean-Strip Green Muriatic Acid will not freeze under normal winter weather conditions, as its unique hydrochloric acid blend drops its freezing point well below sub-zero temperatures (typically between -0.4°F and -50°F depending on the concentration). However, the manufacturer's Klean-Strip Safety Data Sheet still advises storing it in a cool, dry area protected from extreme freezing temperatures. This precaution is primarily to prevent the plastic bottle from becoming brittle, cracking, or leaking due to extreme cold.

Q: Does this harm plants near the steps ?

7 months ago
1 Answer
  • A: Yes, Klean-Strip Green Muriatic Acid can harm or kill plants near your steps if they come into direct contact with the product or its runoff. Even though this "Green" version has 90% lower fumes than standard muriatic acid, it still contains a strong acid (hydrochloric acid) that can burn foliage and significantly alter soil pH.

Q: Will it clean excess hardened grout off pavers

11 months ago
1 Answer
  • A: Yes, Klean-Strip Cleaner can be used to clean excess hardened grout off pavers. However, because muriatic acid is very corrosive, it must be used with caution, and proper safety precautions must be taken. Always perform a spot test on an inconspicuous area first to ensure it won't damage the pavers.

Using an acid solution

6 years ago
This product is so good for many different projects...just remember when diluting it you must add the acid to the water...NOT the other way around or you may get a violate reaction. I found that a 50/50 mix is about perfect for most jobs, and always keep a baking soda/water handy for neutralizing the acid after using it.

I bought 3 gallons and removed the rust in the Farmall Super A tractors fuel tank. Wonderful results. After however I did not seal the tank and got flash rust. I am back to the Tractor store to get another gallon plus a gallon of acetone to clean it dry then a quart of sealer to swish in the tank to cover top bottom and sides. TSC has best prices compared to others in our area of Virginia.

Just what I needed

11 years ago
I looked online for this first and prices were way higher elsewhere. I was able to get this at my local store, and while the jug did not look anywhere near the same as the picture, it was just what I needed at a very good price. I'll be back to TSC for this product (Muriatic Acid) and other home, lawn, and garden needs. FYI, I use the Muriatic Acid in a diluted water solution to clean my swimming pool filters.
