Why Does My Jetted Tub Smell Like Rotten Eggs?

The aroma one feels of a rotten egg when soaking in a hot tub occurs naturally and is best worked upon with immediate effect.

This foul smell is caused by the presence of high levels of sulfur bacteria in the spa system.

Whenever there are high or warm temperatures, the sulfur bacteria react to form Hydrogen Sulfide with almost a similar odour to rotten eggs.

The cause of Hydrogen Sulfide is the tubs water heater.

This foul smell tends to occur mainly in tubs that are heated but not used because of no aeration provided by the air jets, which reduces oxygen supply in the water.

Hydrogen Sulfide is proven to be safe, but the smell that comes with it irritates bathers.

Despite the gas not being harmful to the bathers, it does ruin the tubs since it can corrode metals such as copper that is majorly used in hot tubs because of their heat conducting features. 

How Do You Clean A Smelly Jacuzzi Tub?   

The bacteria that cause the rotten egg smell can only be killed using chemicals and not the typical cleaning materials we know.

The bacteria build up in the water jets and multiply, and so a regular cleanup of the jacuzzi tub is good despite making the once in a while rigorous cleanup.

To clean up the tub, first, you need to flush out all the gunk and bacteria accumulated in the tub’s internal plumbing system. 

Before starting the cleaning process, you need to empty the tub and wipe any debris from the tub’s basin and the rim.

After which, you will add water, hot water, to a level slightly above the jets. After you have filled the tub, you have an array of cleaning agents to clean the tub.

Vinegar is quite acidic, and so this is the easiest and first option one can use to clean up the jetted jacuzzi.

You will need two cups of vinegar to be added to the hot water-filled tub to dissolve the buildup effectively and does not cause any damages to the tub components, unlike other commercial cleaning products.  

You will then turn off the air jets of the tub unless the manufacturer recommends that they should be left open during the cleaning process.

By so doing, the water will circulate through the internal plumbing system of the jacuzzi, which will cause a higher concentration for deeper cleaning.

We will need you, the owner, to run the jets on a high until the debris in the tub’s internal plumbing system stops washing in the water in the tub.

After doing this, the tub is to be drained and filled with warm water once more, and the tub runs on a high to flush out as much gunk left in the internal plumbing system then drain the water. 

After you have drained the water in the tub, you will sprinkle the baking powder all over the tub and let it sit for a few minutes.

You will then get a dampened piece of cloth and scrub it gently to remove the grime on the basin walls.

Finally, you will get a toothbrush that you do not use to wash the jet nozzles and the contour trim around the nozzles.

The tubs air-intake should also be cleaned by unscrewing it from the tub and cleaning separately.

After all, this is done and the air intakes screwed back in place, you will give the tub a topnotch rinse and then be good to go. 

Can you use bubble bath in a hot tub?

It may seem fun to soak in a bubbly tub, but it will not be recommended. Putting a bubble bath in a jacuzzi tub is not harmful to the bathers but will cause harm to the tub.

When we use a bubble bath in a jacuzzi, the air and water jets churn the water, creating foam.

The problem comes when the jacuzzi recirculates the water containing the bubble bath, which runs through the internal plumbing system and back to the jets.

Debris from the bubble bath causes a clog in the pipes and the jets formed by the waste from the bubble bath.

The only place one can use bubbles is when in an air tub but in small amounts.

A clogged water pump will fail to dispense water in the tub, which might cause overheating in parts of the pump leading to electrical fire.

With this, you can still experience the comfort of your jetted tub without turning on the jets, and the bath bombs will work fine. 

On the other side, jetted tubs will be damaged by bath bombs if the bath bomb that is to be used is either glittered, has confetti, too much oil and dye.

Hi! I' am Tom. I was a manager in one of the biggest stores for over 10 Years, am also an SEO by night. I don't like to call myself a blogger; they are very analytical, do email marketing, and know all SEO stuff. I faced many questions from customers about different products, and there was hardly any help on the internet. After learning all the things about these products as a manager the hard way, I decided to start a blog and help other people.
