Q: Can this be used to lower alkalinity in my swimming pool?

2 months ago
1 Answer
  • A: Howdy neighbor! Yes, you can use Klean-Strip Green Muriatic Acid to lower your pool's total alkalinity. Since chemical needs vary drastically by pool size and water balance, you must consult your pool manufacturer's manual or a certified pool professional, and strictly follow all product safety labels to prevent injury or equipment damage.

Q: Does this harm plants near the steps ?

5 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

9 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.

NOT full strength (31%) acid

4 years ago
Give me a break. No indication of strength on the label. I should have looked first. MSDS says "between 10-30%". Seriously? Like, they don't know. It acts like 10% as it takes more than twice as much to get the same results as 31% acid. Just go to the hardware store and buy the real stuff for the exact same price.
SweepstakesNo

No, I do not recommend this product.

Response from KleanStripExpert:
4 years ago
KleanStripExpert
We only recommend using Klean Strip Green Muriatic Acid to brighten concrete, brick, masonry, stone, grout and hard surfaces, and etch concrete and masonry so that sealers or finishes will adhere. More than one application may be needed for tough spots. Without knowing more details about your project and how it was applied, it is hard to say why you did not get the expected results. Even though this is a "green" product, it is still a very strong acid that works great for masonry. You can always call our Klean Strip helpline at 1-800-398-3892 when you have concerns or feedback about our products.
