  • It doesn't mask smells, it neutralises them

How do you know your RV's black water or grey water tanks need treatment?

  • You have smells from vents
  • The pump out from a full tank is less than the tank capacity
  • You can see the waste level in the tank after pump out.
  • A sensor is not working properly

Doses & treatment for RV Holding Tanks

Initial dosage:

The first time you use the product in a tank that has already been in use, you will need to use more at first to clean all hoses and tanks in order to cure the problem. This may need more treatments at a higher dosage rate to start, because RV tanks are not as deep, have a larger footprint and at times are harder to drain.

  • Do not use any other additives
  • Use ½ Tablespoon per person every 2-3 days
  • If the system is badly sludged up you may need to do this twice a day. Same small doses.
  • After emptying, flush one tablespoon into the empty tank. You may need to flush more than once to get it down to the tank.
  • When not using the RV for more than a week flush down one tablespoon/15grams per 20 litres of effluent.    
  • This product is an environmentally friendly surfactant; in waste systems it poses no environmental impact on discharge.
  • When pump out is needed it will enhance the performance of septic fields or other waste treatment systems it is emptied into.
  • The main reaction by-product is sodium carbonate (washing soda)
  • See our Material Data Safety Sheet for full details
  • If you have a vacuum flush make sure no grains are left on the seal, so either wipe them off or make sure they are well flushed.
  • Suggested dosages – Doses don’t have to be exact.
