Cockroaches
We can buy very toxic and expensive insect sprays but I know that window cleaner is more effective.
I wonder which combo of the ingredients does the job on the cockroaches, and how?
4.0% isopropyl alcohol (a highly volatile solvent)
1% ethylene glycol monobutyl ether (a less volatile solvent),
0.1% sodium lauryl sulfate (a surfactant),
0.01% tetrasodium pyrophosphate (a water softener),
0.05% of 28% ammonium hydroxide,
1% of a dye solution,
0.01% perfume
