There are several household products that can be used to clean a hot tub. One option is to mix a solution of equal parts white vinegar and water in a bucket or spray bottle and use it to wipe down the surfaces of the hot tub. Another option is to use a non-abrasive sponge or cloth with Simple Green All-Purpose Cleaner. Some experts advise against using soap and water to clean hot tub covers, as some soap can damage the cover. It is important to rinse the hot tub thoroughly after cleaning to avoid any residue that could affect the water chemistry. When using any cleaner, it is important to follow the manufacturers instructions and avoid using any abrasive or toxic products that could damage the hot tub.
