Is bleach residue (after evaporation) safe?
I have been preparing bleach disinfectant lately in a spray bottle and have been spraying on my couch, door mat, door knots, etc...
I don't rinse it... So I assume there is bleach residue left after evaporation. Is it safe to leave the residue?
I felt some very mild burn like feeling on my arms when putting my arms on my couch lately; I don't know if this is some kind of placebo effect or if it is real.

In the UK most bleach contains NaOH and NaClO. The hypochlorite (which is the bit that does the bleaching) breaks down to common salt and free oxygen. The hydroxide doesn't. So it's possible you are experiencing some kind of chemical burn.
In its manufacturing process, hypochlorite bleach begins as salt and water. After use, the compound breaks down mainly into salt and water during or quickly after use.
So it's table salt left behind, NaCl, as well as the similar NaClO3 and NaOCl.
