RunClean is a descaler unlike any on the market. We needed a solution to clogs and scaling that actually worked. There were many products with claims but everyone still had clogs and buildup in their reservoirs caused by scale. Runclean checks all the boxes. Use it to keep your reservoirs, drip lines, pumps, emitters, sprayers, pots, and tables free from scale and clogs. RunClean is also used to soak parts and equipment that has buildup. RunClean increases mineral availability by dissolving carbonates.

RunClean is not hypochlorous acid and does not increase ORP. Hypochlorous Acid is not an effective descaler. HOCL is used to increase ORP. Increasing ORP is used to keep systems sterile and prevent or eliminate biofilm.

Scale is caused by nutrient solution clinging to the walls of irrigation systems, reservoirs, etc and forming a solid. Scale has nothing to do with nutrient solubility and is seen most often in parts of irrigation systems that go dry regularly, like the reservoir and emitters.  The white "crust" you see on pots and tables is scale. When pieces of scale break off and flow through an irrigation system, it causes clogs.

Cropsalt's Runclean:

  • Completely stable and will not sour your rez like other products on the market
  • Replaces ph down
  • Does not increase or decrease ORP
  • Does not contribute to EC
  • Makes minerals more available in soil applications
  • Prevents calcium "fallout"
  • Acts as a surfactant
  • Eliminates the need for reverse osmosis water in most applications (under .7 EC tap or well)
  • Does not harm microbes
  • 100% environmentally safe
  • Stable when used with chlorine products like bleach and hypochlorous acid
  • Does not interact with silicates
  • 0-0-0 NPK
  • Keeps your wet walls and swamp coolers free of scale
  • Keeps your dosers clean and free of scale if added before your doser panel


Directions for use:

  • If using ph down, use Runclean instead
  • .2-.4 ml per gallon with every feed to prevent scaling and clogs in a clean system.
  • 1 ml per gallon to reduce existing scaling and clogs.
  • 4-8 ml per gallon for equipment soaks and between runs to "reset" and dissolve any scale.
  • Use of a wavemaker in the rez or in your parts soaking container will increase rate of descaling.
  • Contact time directly correlates with descaling abilities.

    Perfect Pair!!

    Must have for anyone running cropsalt in a reservoir! Everything is so clean, clear, fresh it is phenomenal seriously. Love that this product not only keeps my res, lines, pots, clean and clear, but the fact that it doubles as ph down saves so much headache, money, and hassle. Running 6.0-6.1 PH, 2.1 EC, and 1050 PPM... plants couldn't be much happier!!! Thank you all for the outstanding products and service yall provide! Truly for the community! also, I am saving so much money and getting better results... no need to compare or think about whats best, Cropsalt is it!!!

    RunClean Cleans The Competition

    Ran a bunch of scale buildup products in the past. It was so good I actually got clogged lines because of all the build up my previous product was supposed to remove, didn’t. Had a new irrigation setup that started with CropSalt and never had one clog.
