## Questions & Answers

**Q: Can you please provide msds for this product?**
A: The MSDS is very strange, it lists the ingredients as “Monohydrate”. It’s missing the rest of the formula for which monohydrate is a modifier for, so this MSDS does NOT appear to accurately or fully state what’s in the product. Monohydrate in chemistry means each molecule of something (e.g. calcium sulfate) has a single water molecule (H2O) attached.

**Q: What are the ingredients in this product?**
A: Because the product is not ingestable, there is no requirement or law to list the ingredients.  However, in some of the literature they do mention certain combinations of "salts" in the mixture.  Whether TSP or a Zinc compound, they've got it figured out and I am really pleased at the product performance.  :)

**Q: How long can u leave this product in the tank? If we are moving to a location without a dump station can it stay in for days?**
A: We've always followed the directions on the container. I would think you could leave it, however I wouldn't fill the tank with a lot of waste before flushing it out. They make a product for regular use. This is to break down the residual waste build up in your black tank.

**Q: Can you use this product if you 5th wheel is stationary?**
A: If you can add enough water to cover the sensors, then I would imagine it would clean them.  I agree with the previous post, sloshing around helps to clean the tank.  I found this in the product description, " Stationary units require more rinsing with less success.. . ."  If you add the recommended amount of cleaner, add enough water to cover the sensors, let it set for awhile (I would guess at least an hour- just a guess), then rinse several times, it might work.  We have only had to use it once and the sensors worked like new again.
