Black stains on silicone sealants are most likely mould and can be triggered by elevated moisture levels, inadequate air circulation, organic debris on the sealant surface (including soap, shower gel and shampoo), and elevated temperatures in bathrooms and kitchens. It can produce unpleasant odours, harm fixtures, and potentially extend across walls, ceilings, and floors.
Households are prone to notice mould appearing as black marks on sealants surrounding windows, sinks, bathtubs and showers. It can be challenging to eliminate black mould from silicone sealants, given how stubborn the growth is. Nevertheless, one cleaning enthusiast has posted to the Mrs Hinch Cleaning Tips and Tricks Facebook page to share how they managed to address the problem with "no scrubbing and no cleaning", just white vinegar.
Sandra Gibson posted: "I am by no means Mrs Hinch, but I do like a nice clean bathroom and have struggled with black spot marks on my sealant.
"We saw a post where you place some vinegar on the affected area and place a cotton pad (can use kitchen roll too) over the top and leave.
"After forever trying different cleaning chemicals, I didn't have a great deal of hope, but I thought it was worth a try.
"Omg, thank you to the person who posted this hack! No scrubbing and no cleaning, just pick up the cotton pads the next morning and wipe them down. I'm in cleaning heaven. I hope this helps someone else."
Sandra shared photographs of three sections of black mould on the silicone sealant surrounding her bath and shower, along with another three images of the same spots during and after the cleaning procedure.
In the photos displaying her results, no traces of mould remained on the sealant. The cleaning post accumulated over 300 comments from fellow group members expressing their views on this tip.
Claire Lucas said, "I did the exact same, and wow, it really does work. No more black spots."
Brown Lottie wrote: "Yeah, this works well. I use a kitchen roll as it covers a bigger area. Another good one is to use the Astonish Mould and Mildew spray. You spray and leave, it does the same, and the mould is also all gone overnight."
Francis Oliver advised: "Just spray the area with vinegar once a week. It works fast and will keep mould away."
Numerous households may already possess a bottle of vinegar tucked away in their kitchen cupboards, but for those who haven't got any, it's inexpensive to purchase at supermarkets.
