Cleaners that touch the LP  can cause damage by flattening the lands, the delicate area that separates the grooves, distorting the information locked in the grooves. Dirty / crusty
pickup tubes will damage the lands. The inrush of air developed by a vacuum cleaner can dry an amount of the cleaning agent before it is removed  leaving a residue behind.

My system uses  a simple device that cleans the record without  touching it. This is a form of hydraulic cleaning. The LP is mounted on a rotating mandrel.  Protective label covers repel the water. The Super Solution agent is applied to the LP surface to loosen the contaminants. 
A jet of water from an orifice is applied to the groves at a angle that flushes away the debris. A  Culligan RV 800 filter can be used where water quality is poor.

Note: This is the only method that has a chance of recovering a flood damaged LP
