Due to your moving company
not allowing the transport of toxic cleaning agents as a part of the packing
and transport process, you will need to be certain that you dispose of these items properly. If you don't want to take the items to your new residence on your own, there are some tasks that you will need to take care of to make sure the process is safe.
Read the directions on the can or bottle, as many household items with harmful chemicals will clearly explain what needs to be done for disposal. The methods of disposal can vary, but if it is harmful to others or the environment, it will likely say not to pour it down the drain or outside of the home.
If you aren't sure what the situation is with a certain product, but you know it is able to go down the drain, there shouldn't be a problem getting rid of it. This typically works for soaps and other items that aren't dangerous to the environment. Water-soluble items are always good to let down the drain, as the water breaks them down soon after mixing.
However, not all cleaning agents give you this option. When in doubt, go to the local trash facility, and speak with a representative about disposal of these items. These destinations will usually have a chemical disposal area, and if they don't, someone will be able to direct you in an area that does have them.
Remember to take care of these items before you finish packing and leave the home. Knowing that you can take care of them properly is better than someone coming across these chemicals and not knowing what to do.
