How to remove silicone sealant mould fast for 65p without scrubbing

Aug 17, 2023

Black mould growth on silicone can be sparked by high levels of moisture, poor air circulation, organic waste materials on the sealant surface (such as soap, body gel and shampoo), and warm temperatures in bathrooms and kitchens.

This growth can be smelly, damage fixtures, and potentially spread across walls, ceilings, and floors.

Households are likely to see mould growth in the form of black stains on sealants around windows, sinks, bathtubs and showers.

It can be hard to find out how to remove black mould from silicone sealant because of the sheer volume of information available online.

However, one cleaning enthusiast has taken to the Mrs Hinch Cleaning Tips and Tricks Facebook page to share how they were able to tackle the task with “no scrubbing and no cleaning”.

Tamara King wrote: “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 a little bit of bleach 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 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 after a few hours and wipe them down. I’m in cleaning heaven. I hope this helps someone else.”

Tamara posted pictures of three areas of black mould on the silicone sealant around her bath and shower, and another three pictures of the same areas during and after the cleaning process.

In the pictures showing her results, there were no signs of mould left on the sealant. The cleaning post received over 280 comments from fellow group members sharing their thoughts on this hack.

Claire Lucas said: “I did the exact same and wow, it really does work. No more black spots.”

Brown Lottie commented: “Yeah this works good. I use 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 instructed: “Just spray the area with bleach once a week. It works fast and will keep mould away.”

Many households will already have a bottle of bleach stored away in their cleaning cupboards, but for those who don’t, it is cheap to buy at supermarkets. Bleach retails for 65p at Asda and 70p at Tesco and Sainsbury’s.

While the post received positive responses, one cleaning fan urged caution for those using bleach.

Emma Statham said: “Just be careful of the chrome part of the shower door - I did bleach with cotton wool and it affected the chrome by leaving a mark.”
