Pour 3 cups of lukewarm distilled water into the pitcher. Then add 1 cup of isopropyl alcohol. Stir the solution together with your hands until it becomes uniform. Pour the solution into the spray bottle and screw the lid on tight.
Spray your microfiber cloth with the solution about two or three times, enough that the cloth becomes visibly wet but not oversaturated. Then wipe down the record, top and bottom, following the grooves. Make large circles, moving from the outside to inside. Put more effort into the outermost grooves where you place the needle to play the record. These are the ones that tend to attract the brunt of fingerprints and dirt.
Put a stopper in your sink and fill it with a gallon of distilled water. Then dunk the record in the sink to rinse off the cleaning solution, wiping it with a new microfiber cloth as needed. Do not use tap water unless absolutely necessary because it could deposit minerals on your record.
Pat the record dry with a third cloth. Do not rub it. Dry it quickly so water spots don't have a chance to form. Make sure the phono record is completely dry before you put it back in its case.
