SE Nebraska, Near Misery and Cans Ass! | boog - 2/26/2021 20:06 I wash them out with a hot water pressure washer turned up as hot it will go. Drain then fill with ~ 50 gal of water + 1/2 gal ammonia, hook pump to outlet, screw cap on top that has a rinse ball and run pump for approx 30 minutes, drain, add clean water & rinse again for 30 minutes, drain water and vac out any remaining water with a wet vac. Soap and cooking oil are no big deal and I don't think the car wash products would be either. Hot water wash and drain will be sufficient, ammonia and cooking oil don't mix. The rinse from the dish soap would be good to remove the cooking oil. |
