Soiled, grubby, and filthy bathtubs are a nasty sight themselves. They not only multiply bacteria and germs but also have spots and stains that can adversely affect your skin. And regular cleaning agents like lime and dish soap will do little to discard those tough stains. So, how do you clean a bathtub perfectly?
One of the most effortless ways is to bleach them. But, since bleach is a caustic material, is it safe to use it for cleaning bathtubs? Or does bleach damage bathtubs? If yes, how do you use it without compromising your bathtub’s quality? Let’s analyze it all here.
Although bleach is a strong bathtub cleaner and disinfectant, it can damage or discolor the bathtub surface if used excessively or undiluted. Some bleaches, like chlorine and oxygen bleach, are more corrosive and do more damage than regular household or diluted bleach.
Which Bathtubs Can You Bleach?
Generally, smooth bathtub materials withstand the harshness of bleach and have a polished, protective layer that resists further abrasion. In contrast, textured and coarse bathtubs weather off easily with bleach. So, let’s explore the bathtub materials that look refurnished with bleaching.
1. Can You Bleach a Porcelain Bathtub?
You can bleach a porcelain bathtub, but do not scrub and wash it excessively as the sensitive porcelain might chip off easily. Instead, cover your bath with paper towels and air-spray bleach using a spray bottle, and let it sit for about 30-45 minutes before removing the towels.
After that, rinse the bathtub with any non-abrasive cleaner and warm water and wipe it gently with a microfiber cloth to prevent any oxidation or discoloration.
Quick Tip: Use diluted oxygen bleach with colored or textured porcelain bathtubs, while you can use harsher chlorine bleach for white porcelain bathtubs.
2. Can You Use Bleach on a Fiberglass Bath?
Yes, you can directly use bleach on a fiberglass tub, but since it’s slick and polished, you must evenly dab the bleach using a soft sponge and microfiber cloth. You can also spray it using a spray bottle, let it sit for 15 minutes, and then rub it off with a soft scrub and cold water.
Moreover, if you have an acrylic-enamel finished tub. In that case, it’s advisable to dilute the bleach with equal water to prevent discoloration and weathering of the top coat.
Alternatively, mix about three parts of bleach and one part of water to remove the rust or hard water stains of your resin-coated fiberglass tub. Either way, avoid excessive scrubbing and scraping as it may damage the top glass coat and expose the bleach directly to the plastic underneath.
Quick Tip: You can apply a thin layer of elbow grease to your fiberglass bathtub to keep its resin coat intact after bleaching.
3. Can You Bleach a Stone-Resin Tub?
You can clean a stone-resin tub with regular bleaches instead of oxygen or chlorine bleach. First, rinse your bathtub with a diluted bleach solution of one part of household bleach and fifty parts of water, and then dab it using a microfiber cloth in circular motions.
Also, scrub it with any non-abrasive tile cleaner or toilet bowl cleaner to help hide the minor scratches and chips that might stand out more after bleaching.
Quick Tip: Natural stones might discolor a bit on excessive and repetitive bleaching. Hence, you can coat them with a clear coat of polyurethane sealer to add more shine.
4. Can You Bleach a Plastic Bathtub?
Bleach can discolor and damage a colored plastic tub, but you can use it to disinfect and refurnish a white plastic bathtub. Spray a thin layer of diluted beach to cover the mild stains, raw household bleach for tougher stains, and harsher chlorine bleach to remove mildew and soap scum build-up in plastic baths.
Quick Tip: Scrub a white plastic bathtub using bleach and a soft-bristled toothbrush for about 15 minutes to remove all the yellow stains and prevent mold.
5. Can You Use Bleach on a Cultured Marble Bathtub?
You cannot use corrosive chlorine or oxygen bleach on a marble bathtub, but a diluted bleach solution can be used to remove mild, yellow stains. Also, do not let the bleach sit on its surface for more than 15 minutes before rinsing it off with a non-abrasive bathtub cleaning agent and water.
Quick Tip: Once bleached, apply wax, polish, or any sealer onto the marble surface after a minimum of 24 hours for a smooth finish.
Which Bathtubs Don’t Withstand Bleaching?
- Acrylic Bathtub: Bleach destroys the top finish of any acrylic tub and may add bumps, craters, or even holes to its surface. Plus, you may lose the warranty of your acrylic tub on bleaching it, thus, leaving you with permanent damage. However, you can use powdered oxygen bleach on acrylic as a disinfectant once a year.
- Cast Iron Tub: Bleaching cast iron tubs will leave you with red streaks and rust stains all along the surface of your tub, damaging the tub color permanently.
- Copper Bath: Bleach reacts with copper’s natural patina, stains, and discolors its surface, making it look old and shineless.
- Wooden Bath: Bleach corrodes the surface of most of the popular bathtub woods like Teak, Cypress, Mulberry, and Cedar. Bleach seeps in through the layers of the timber and tears the surface, making the tub unfit for use.
- Crystal Tub: Crystal tubs are transparent and porous. Thus, bleach percolates down to the bottom and adds a whitish bathtub stain that might look repulsive from the outside.
- Enamel Tub: Enamel tubs have a thin, resin-like finish that tears and melts with bleaching, adding holes and uneven finishes that are unfit for use.
How to Clean a Bathtub With Bleach?
Working with volatile bleach requires care and caution, or it might damage your skin and irritate your eyes. So, before you begin bleaching your bath, here are a few essential tips to keep in mind.
- Ventilate the room, open all the windows and turn on the exhaust to eliminate all the poisonous fumes during bleaching. Additionally, wear a face mask for more protection.
- Wear rubber gloves to prevent direct skin contact with bleach, and use safety glasses to protect your eyes.
- Cover your tiles with paper or towels to prevent accidental bleach stains, and clean them with a tile cleaner once you finish bleaching.
