My experience with dipping baskets in general, is that they work great for items that don't hold water. Items that do hold water require a bit of care not to spill, but should work just fine.

If you decide to go with a standard bucket without markings, don't forget to add some sort of "max fill line" to the bucket. Otherwise, the fluid coming out of the holes can spill out because people don't always lift the basket slowly enough to prevent that.

Thank you,

Has anyone used this 5 gallon bucket with dipping basket combination?
If so, what was your experience?

We use similar style round tanks for manufacturing, and even with the lip to keep splashes from escaping, they aren‰??t safe to be moved if they‰??re over half full. You can buy them with spigots, though, and that makes them easier to empty and clean. The spigots are likely a source of leaks, though, and can be knocked off fairly easily.

Depending on the kind of gasket, the material in the bath can degrade the gasket and keep the buckets from sealing properly. I like the containment buckets that are used to overpack returns of hazardous materials. The larger ones have handles molded in and locking lids.

Some groups are using 5-gallon buckets with poorly fitting lids, which is what led to the spills. In updating our recommendations, however, we questioned whether or not the lids should be tight-fitting (liquid/gas tight) due to the potential for pressurization.
