Probably not — much like all the perpetrators mentioned earlier. In purchasing supplies, I was recorded on store security video and the store has records of my purchase. Such video or paper trails are often revealed during investigations, and are one of the main reasons why chemical disposal research is performed; if investigators know whether an acid or base was used they can check who purchased or had access to such chemicals.
Indeed, when employing chemistry to destroy a corpse, it is likely that only partial destruction will occur. Even with the small samples I treated over a series of days, there was still remaining material available for analysis.
Schuster learned this lesson the hard way. Investigators easily located the unit with help of a witness and a paper trail, and readily identified the remains.
In she was sentenced to life without parole. And even if the disposal is successful, as in the case of Haigh, police work can still solve the crime.

Acidic drain cleaners made of sulfuric or hydrochloric acid are powerful enough to clear heavy-duty hair, food, grease, soap scum, or paper-based clogs in 15 minutes or less. Acidic drain cleaners are generally safe for newer plastic or metal pipes e.
Breathing sulfuric acid mists can result in tooth erosion and respiratory tract irritation. Drinking concentrated sulfuric acid can burn your mouth and throat, and it can erode a hole in your stomach; it has also resulted in death. If you touch sulfuric acid, it will burn your skin. Mix one part muriatic acid to five parts water and slowly pour that solution into the toilet bowl. Add just enough to come up to the normal water level in the bowl. If you add any extra, it will go down the drain line toward your septic tank.
Let the acid solution sit in the bowl for two to three hours. Chemical reactions that result from sodium hydroxide, sulfuric acid, and hydrochloric acid generate a lot of heat. Acidic drain cleaners usually contain sulfuric acid at high concentrations.
It can dissolve cellulose, proteins like hair, and fats via acid hydrolysis. Acid solutions used on a regular basis will destroy iron pipes and is harmful to older porcelain fixtures. Muriatic acid may not hurt PVC or other drain lines, but it is much too aggressive for monthly maintenance and it is potentially dangerous to use if not careful.
Oxidizers, acids, and caustics are examples of drain cleaners that can cause PVC pipes to melt or become soft. Sulfuric acid and hydrochloric acid are the active ingredients of acid cleaners.
The general rule of thumb is that hot boiling water can soften or even slightly melt the joints in your PVC pipes so YES, if you subject these types of pipes to high temperature water on a regular basis — they can be damaged, causing leaks and eventually requiring replacement.
Hydrochloric acid will not react well with fat but one possible side reaction might give off chlorine gas. The precautions necessary for either of these would be rather high, compared to using 10M NaOH, which will essentially turn your fat into soap, which then dissolves and runs down the drain. Sulfuric acid is naturally occurring and is sewer and septic safe as it is diluted in its journey down your pipes. Hydrochloric acid is made from hydrochloride mixed with water and is a very strong chemical that can almost instantly dissolve the soap and hair that is clogging your drain.
Many plumbers prefer muriatic acid over Drano. The normal pH of hair is 5. Any deviation from 5. Coke and Pepsi contain phosphoric acid, which, if left in your drain for one to 2 hours should dissolve build up in your drains. Then you run hot water down your drains and the gunk should be flushed down the drain. Why Drano is Dangerous Drano sits in a pipe until the clog dissolves, continually reacting and generating heat.
Toilet bowls can crack. PVC pipes can soften and eventually break. Old, corroded pipes can be easily damaged, and Drano can quickly eat away at the glue holding pipes together. Overall, plumbers say the best way to clean out clogged drains is by mechanical means plunging and snaking and some hot water.
Stay away from chemical cleaners as they can damage your pipes and are hazardous to humans. The enzyme is totally safe for pipes and fixtures and actually breaks down the oils, solids and wastes inside the plumbing pipes, safely and inexpensively. Rid-X does NOT clear up existing clogs. It is used after a clog has been properly cleared, and as preventive tool to reduce the occurrence of clogs in the future.
