    Solution to clean DE grids???

    Hey there. I am cleaning my DE filter for the first time. I am going to pull out the elements and give them a good washing. Is there a solution I can make myself to really get them clean? I dont want to pay an arm and a leg for some solution from the pool supply store if I can make some myself. Thanks for the help!!

    Many people use TSP, about one cup per five gallons. You can get TSP at most hardware/home centers. I have heard people also use dishwasher powder. You may need to soak in dilute muriatic acid if there is significant calcium scaling.

    Good luck.

    generally, a good high-pressure spray does a fine job (just water).

    If you can't find real TSP, avoid the fake phosphate free stuff, you can use automatic dishwasher detergent instead.

    I am using a muratic acid water mixture. I got most of the stuff off with a really strong nozzle of water. I think the acid/H2O mixture will knock the rest off.


    Thanks for the help.

    You don't want to use acid without first using a degreasing agent like TSP. Organic oils on the filter can harden and permanently damage the filter if they are still there when you use acid. Usually TSP, or automatic dishwashing detergent, is enough to take care of everything. But if you have calcium scaling on the filter you follow the TSP with acid to remove the calcium buildup.
