To clean Jacuzzi tub jets, fill the tub with hot water, add low-sudsing dishwasher powder to the water, close the air intake, and operate the pump for 15 minutes. Drain the water, and refill the tub with cool water. Operate the jets for another 10 to 15 minutes to rinse.
Some manufacturers recommend adding 1/2 cup of household bleach to the tub along with the hot water. Another option is purchasing and using cleaners specifically made for hot tub cleaning. Avoid the use of abrasive household cleaners on the tubs or jets as they can cause scratches and damage the tub.
Owners should clean Jacuzzi tubs every 30 days to keep them working correctly. If the tub sees heavy use, the jets require more frequent cleaning. Clean the tub surfaces using a soft cloth.
Oil-based bath products are usually not good for whirlpool tubs. They leave a sticky residue inside the pipes that is difficult to remove and could ruin the pump. For a cleaner tub, avoid these products prior to using the tub.
Tubs filled with hard water require more frequent cleaning. Hard water leaves a scale on the tub's surfaces and in the tub's plumbing that becomes progressively more difficult to clean. Use the manufacturer’s recommended products for cleaning hard-water residue from the tub and pump system.
