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,CH,CH,CH,CH,CH,CH,CH,CH,CH,NH,, R&mdash;O&mdash;(CH,),NH,and R&mdash;O&mdash;(CH,),NH(CH,),NH,wherein R is an aliphatic hydrocarbon having from 8 to 10 carbon atoms, R optionally having additional ether linkages such as C,H,&mdash;(O&mdash;CH,CH,),&prime;, and wherein n is an integer from 8 to 10 and n&prime; 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.
