May have put this in the wrong spot. Sorry. Recently purchased 2 food grade Ibc totes. one t contained molasses and one glycerine. Curious if any of you have experience cleaning these things out. Was thinking about bringing them to a car wash to rinse any residues, but would like to clean them further As I will be using the to store water for plants. Thanks
I wash mine after each winter with a power washer similar to those at the car washes. No soap, just high pressure water. It works well. Once considered using bleach &/or hydrogen peroxide to help but never found that to be necessary. I try to avoid even trace residual amounts of chemicals in the garden. For that reason I would be hesitant to use the glycol IBC for food gardens but realistically that would probably be ok after a good power wash.
A first flush diverter or some other pre-filtering goes a long way towards keeping captured rainwater containers clean.
Argue for your limitations and they are yours forever.
I've had to clean some with brown rice syrup residue, in coldish weather.
Hot water was critical, it was just futile without. I used a garden hose run straight to the landlords hotnwater tank, a sprayer, a tiny bit of dish soap and a fair bit of patience. (The pressure washer wouldn't start... I'm sure it would have helped, as long as I ran hot water through it.)
I washed them in the same area the landlord would pressure wash the heavy equipment, so didn't feel too bad about a few drops of soap in that context!
How do you guys pressure wash the inside top of the IBC? I can see how you could reach in and do the sides and bottom easily enough. Do you reach your whole arm in so that you can shoot the water back at the top?
FYI I've heard that they make IBC tank liners that you can buy. Might be an option if someone has a non food grade one. I'm not sure how they work down at the outlet valve.
