Cleaning Up Used Grow Bags

Greg_Midi · Sep 14, 2025

This is my first time using cloth grow bags, I had a couple on vivosun auto-watering bases and was quite happy with the way that all worked but now I pulled one, and soon the other, plant. These two plants got RO water exclusively and this particular plant used a lot of it. I emptied the bag, soaked it in water in a bucket, let it dry out and then used a scrub brush to knock off a lot of the scaly build up. It looks a lot better and is probably ok to use again but I'm wondering what methods others may be using to clean these things up; throw it in the washing machine, use a special cleaner to spray/soak it, etc.?

I’ve been using the same bags for four or five years! Outdoors! I just fill up a 50 gallon garbage can full of water, throw some bags in and leave them submerged for 24 hours! Stirring with a big stick every once in a while or sticking my arm in! Pull them out and let them dry and throw some dirt in them! Probably doesn’t do Jack! But makes me feel better! I think they are machine washable also!

did you water plants from the bottom? or bags sitting directly on saucers with no airflow underneath??

Good morning from a lady grower who does re use these bags until they get holes LOL i do hand wash inside out in my sink then toss into washer with alittle soap and hang dry. If those are first use bags my goodness just wash them up they'll be good for many grows.

Rt in the washer.
If you don't have a work washer ( live stock blankets, bandages, towels etc...).

Bring them to the laundry mat.
Vinegar and baking soda...
