If the stuff has been in your home for 2 months, most parasites, bacteria and viruses are probably dead. I guess the highest chances of survival have things like mold (if there is any moisture left) and microscopic critters like mites.

I assume you have a N95 / FFP2 filter mask available. Wear a fresh one when you unpack the objects. Keep the windows wide open while you do that and for an additional 30 minutes after you're finished. If there's visible dirt on the floor, it's better to wipe it away with a wet rag than to vacuum it. If you are afraid for your health, ask a friend or family member to do the unpacking.

Textiles or books

Textiles that can survive heat (like cotton, linnen, denim) should be washed on the hottest program. That kills anything there is to kill in them.

If you have a freezer (and some space in it), you can kill parasites and insects by putting the objects into a plastic bag and into the freezer for 2 weeks. This can take care of things like lice, fleas and intestinal parasites from poo, but some molds and bacteria can survive this treatment.

If your books got wet or there is questionable dirt in them, you can try gently heating them to no more than 120°C / 250°F for at least one hour (probably more because books don't conduct heat very well). Put a clean paper towel on a baking sheet and the book(s) on the paper towel, but take special care that no paper touches the top, bottom or sides of the oven or it might catch fire. To help heat all the pages evenly, put small wedges of folded kitchen towels between a few pages to let air flow between them.

If your books already have visible mold on them, the safest course of action is to wrap them tightly in a plastic bag and throw them away. Inhaling mold spores is a health hazard you should not expose yourself to. Wear a filter mask while handling moldy objects.

Metal or plastic objects

Any plastic or metal objects should be manually cleaned of big chunks of dirt and then put into the dishwasher on the hottest setting with the usual dishwasher detergent. Do not increase the amount of detergent. The temperature takes care of any bacteria and mold. If you're afraid that residual dirt might remain in the dishwasher, clean the filter and let it run empty with the short program. This is only to flush out any remains, the germs are already dead.

Metal objects that don't fit into the dishwasher can be heated in an oven. Turn the heat up to 180°C / 360°F and leave the object in there for at least one hour. If available, turn on the fan inside the oven to distribute hot air evenly around all objects. This is obviously not viable for any object that contains plastics.

Small plastic items can be collected in an airtight sealable container. Pour about half a cup of ethanol, rubbing alcohol or bleach into the container and seal it up for at least 30 minutes. Then open the container (outside or in a well ventilated room) and wait until the remaining liquid evaporates.
