Abstract
A method for cleaning the interior surfaces of a receptacle holding a body of water comprises providing the receptacle, providing an aqueous solution having from about 1 to about 100 weight percent of an aliphatic amine or salt thereof, adding the aqueous solution to the water within the receptacle. The aliphatic amine is selected from among the following: CH.sub.3 CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 NH.sub.2, R--O--(CH.sub.2).sub.3 NH.sub.2 and R--O--(CH.sub.2).sub.3 NH(CH.sub.2).sub.3 NH.sub.2 wherein R is an aliphatic hydrocarbon having from 8 to 10 carbon atoms, R optionally having additional ether linkages such as C.sub.n H.sub.(n+1) --(O--CH.sub.2 CH.sub.2).sub.n ', and wherein n is an integer from 8 to 10 and n' is an integer from 1 to 5. When the aqueous solution is added to the water, flocculus or precipitants are substantially not formed in the water proximate to the point of addition. Also disclosed is a swimming pool having a liner and a body of water within the liner. The body of water has from about 1 to about 100 parts per million by weight of an aliphatic amine or salt thereof.
