Chemical cleaning DE filter grids

[JFarr]

Afternoon all,

I'm going to be acid soaking my filter grids in accordance with these instructions. I will be soaking them in a 30 gal plastic trashcan.

The second step reads "Add some TSP (tri-sodium-phosphate) to the water or some electric dishwasher detergent".
Can someone give me an idea what "some" means? A cup? A pound? Several pounds?

Also, I can't find automatic dishwasher detergent that doesn't have some kind of sent or other additives. Is that ok?

Thank you for your time.

Soak grids in automatic dishwasher powder such as Cascade or Electrosol. Use one cup per every 5 gallons of water and soak for at least one hour to overnight. Use a soft brush to carefully scrub the grids if anything is sticking to them and then hose them off.
