What do you mean by no trace of that substance?
Using forensic chemical analysis, zero residual traces of Zyklon B was found within the physical structure and soil of Auschwitz's "gas chamber showers"... whereas the building that were used to sterilize lice infected clothing using the same gas, definitively showed significant traces of the deadly gas when their structures were testing using the same forensic chemical analysis.
The showers at Auschwitz were forensically and definitively proven to never have been used to gas anyone.
Nobody was gassed in the showers at Auschwitz, including your neighbor's parents.
Here's an interesting video that goes into those specific details, if you're interested:

Have you considered the story your neighbor told you is only a half truth?
Perhaps your neighbor's parents did die in Auschwitz but they weren't gassed but starved to death in 1947, two years after the war ended, during what historians refer to as "Eisenhower's Holocaust". Ten million German civilians and one million Jewish prisoners starved to death during this time, which was caused (mostly) by allied sanctions.
We've all seen those photos of German prison guards filling burial pits with the corpses of starved prisoners, but most people don't realize those photos were taken two years after WW2 ended.
Your neighbor may be shy about admitting that his parents remained in Auschwitz after the war ended because they were not released as prisoners of war, but were legitimate criminals who participated in the German Jewish Communist Party (KPD) coup of 1933 and were tried and found guilty of treason.
He may be shy about admitting his parents were the treasonous communist who created Antifa in 1930 and declared a holy war against German Christians in 1933.
