‘My son is a plumber and always told me to never use bleach in the toilet,’ said one. Added another: ‘Hubby a plumber and has always said never use bleach.’
Said a third: ‘Bleach destroyed our toilet so badly it was uncleanable and had to be replaced. I’ll never use it again. It DOES damage the porcelain and the scoring is impossible to clean after that.’
Said one more: ‘I worked in a hotel after many years this happened many needed replacing for this reason.’
However many of the group’s followers disagreed with the advice, with scores revealing they’d been using bleach in their toilets for decades with no issue.
‘My mum has been cleaning the toilet with bleach for over 24 years and no problems yet,’ said one. Added another: ‘50 years....been using beach....! Never had an issue...’
Said a third: ‘Using bleach in the loo for over 30 yrs...no drama at all.’
Added another: ‘I have used bleach gel all of my life no issues and my mum cleans hers daily with it for 20 yrs and she has 2 in the house so i think she is telling a porky.’
Said one more: ‘What a load of Twaddle. 20+ years of using bleach in/on and around the same toilet and it’s still flushing just fine - and the porcelain is still white 👍🏻’
So who’s right? Plumbing website PlumbingSupply.com agrees that bleach can be definitely be problematic on some types of porcelain and toilet systems.
‘Bleach, among the most revered of cleaning products and one that most people have readily accessible, can wreak havoc on your enameled fixture.’ they say. ‘While generally safe with straight porcelain and fireclay, chlorine bleach can oxidize the iron of an enameled fixture to create terrible rust stains. With colored porcelain enamel, the effect can be even worse: in addition to rust, the color will fade.
‘As a general rule, do not use regular chlorine bleach on a porcelain-enameled fixture. When used on straight porcelain or fireclay, follow the dilution directions on the bottle, don't let it sit for too long, and be sure to rinse well and dry after cleaning.
‘As always, never mix cleaners, and be extra-cautious with bleach (especially if you've used ammonia-based cleaners previously). If your home has a septic system instead of municipal sewage, steer clear of bleach as it can quickly destroy the natural waste-disposing ecosystem of your septic.’
