Cleaning methods encompass solvent cleaning, hot alkaline detergent cleaning, electro-cleaning, and acid etch. In industrial settings, the water-break test is a common practice to assess machinery cleanliness. This test involves thoroughly rinsing and vertically holding the surface.
Parts washers were originally developed for use in automotive transmission and engine repair shops as a way to improve the function of simple soak tanks.Soak tanks are vats filled with a mixture of water and detergent, which take hours to "soften" the built-up road grime, fluids, tars and oils enough to be manually rinsed off prior to disassembly and repair.
As one of the most widely used rehabilitation methods, CIPP has applications in sewer, water, gas, chemical and district heating pipelines ranging in diameter from 0.1 to 2.8 meters (2–110 inches). The process of CIPP involves inserting and running a felt lining into a preexisting pipe that is the subject of repair.
Roto-Rooter's sewer cleaning service allowed homeowners to avoid digging up lawns and landscaping to reach underground sewer pipes. This breakthrough was a revolutionary concept. In the 1930s and 40s, Roto-Rooter featured an illustration of a mound of dirt over a recently excavated sewer pipe with the caption, "Why put a grave in your yard?"
Due to the vigorous reaction between the acid and water, such acidic drain openers should be added slowly into the pipe to be cleaned. Acidic drain openers (in very high concentrations) hydrolyze proteins and fats via acid hydrolysis (acid-catalyzed hydrolysis), similar to their alkaline versions: RCONH 2 (amide or proteins) + H 3 O + → NH 4 ...
In an internal combustion engine, a head gasket provides the seal between the engine block and cylinder head(s). Its purpose is to seal the combustion gases within the cylinders and to avoid coolant or engine oil leaking into the cylinders. [1] Leaks in the head gasket can cause poor engine running and/or overheating.

Pigs are used in lube oil or paint blending to clean the pipes to avoid cross-contamination, and to empty the pipes into the product tanks (or sometimes to send a component back to its tank). Usually pigging is done at the beginning and at the end of each batch, but sometimes it is done in the midst of a batch, such as when producing a premix ...
