How to Clean a Whirlpool Bath

Unlike a normal bathtub, a whirlpool bath has jets, pipes and a pump; a ring of soap and body oil forms on its surface, residue collects in the jets and water residue builds up in the pipes. Most home whirlpool baths are acrylic; the surface is cleaned with a neutral cleaner and a soft sponge, while the pipe system is maintained with the method recommended by the manufacturer. This guide explains how to clean the inside and jets of a whirlpool bath and a yellowed whirlpool bath. For ordinary bathtubs, see the guide how to clean a bathtub.

Before you start

Cut the power: switch off the pump and, if possible, turn off its circuit breaker.
Read the manual: the whirlpool manufacturer's cleaning and care instructions always come first.
Know the surface: most home whirlpool baths are acrylic; acrylic is damaged by abrasive and acidic products.
Drain the water: empty the whirlpool bath and remove hair and debris.

How to clean the inside of a whirlpool bath: step by step

Add START all-purpose surface cleaner to lukewarm water in the amount on the label. According to its safety data sheet, our START all-purpose surface cleaner has a pH of 7–8.
Starting from the ring at the waterline, wipe the inside surface, seats and edges with a soft sponge.
Clean around the jets with a small soft-bristled brush.
Rinse the whirlpool bath with plenty of water; detergent residue makes the surface slippery.
Dry the surface and fittings with a microfibre cloth.

Whirlpool jets and pipes

Remove residue around the jets and on their covers with a soft brush; if the manufacturer allows, take off removable jet covers and wash them in warm soapy water. We have no product for cleaning the inside of the pipes and pump; to clean build-up in the pipes, use the whirlpool pipe cleaner recommended by the manufacturer according to its instructions and run the system with plenty of water to rinse it. If bad smells or discoloured water come from the pipes, contact an authorised service. If the whirlpool has a filter, take it out and wash or replace it according to the manufacturer's instructions.

Foam and yellowed whirlpool baths

Foam: excess foam in a whirlpool bath mostly comes from the residue of bubble bath, shampoo and oily bath products; do not use foaming products in it and run the system with clean water to rinse.
Yellowing: yellowing in a whirlpool bath is mostly a build-up of soap, body oil and limescale and lessens with regular cleaning using a neutral cleaner.
Permanent discolouration: discolouration of acrylic that has yellowed with age or been scratched may not go away with cleaning; consult a company offering bath refinishing.
Limescale marks: limescale remover is not used on an acrylic whirlpool bath; marks are removed with a neutral cleaner and soft sponge, and limescale does not build up if the bath is dried after use.

Spas and hot tubs

In outdoor spas and hot tubs, the water circulates continuously; water care and disinfection use the water care products and methods recommended by the manufacturer. We have no product or claim in this respect. When the water is drained, the shell surfaces and cover can be wiped with diluted surface cleaner and rinsed; follow the manufacturer's advice for the cover and trims.

What not to do

Using limescale remover, hydrochloric acid or bathroom and toilet cleaner on an acrylic whirlpool bath.
Using steel wool, abrasive powder and hard brushes.
Using solvents such as acetone and thinner.
Letting water or cleaning product get into the pump and control panel.
Mixing different cleaning products together.

For hotels and spas

Whirlpool baths in hotel rooms and in spas are cleaned after every use; wiping the surface with a neutral cleaner and rinsing it, and maintaining the pipe system at the intervals set by the manufacturer, keeps the routine orderly. Where hygiene and disinfection are required, follow your business's procedure and the relevant regulations. For room bathrooms, see how to clean a hotel room, and for hammams and wet areas, how to clean a hammam.
