Remove Black Stains from Silicone Sealant Overnight with a Common Kitchen Item

Cleaning enthusiasts have revealed a simple method to eliminate black stains from silicone sealants without scrubbing or heavy cleaning, using just one household item.

What Causes Black Stains on Silicone Sealant?

Black marks on silicone sealants are usually mould caused by factors such as high moisture, poor ventilation, organic residues like soap or shampoo, and elevated temperatures common in bathrooms and kitchens. These stains not only produce unpleasant odors but can also damage fixtures and spread to walls, ceilings, and floors. They often appear around windows, sinks, bathtubs, and showers.

Effective Cleaning Hack Using White Vinegar

Removing black mould from silicone sealants can be challenging due to its persistence. However, Sandra Gibson shared a straightforward and effective solution on the Mrs Hinch Cleaning Tips and Tricks Facebook page:

"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 hope this helps someone else."

This simple treatment uses white vinegar applied with a cotton pad left overnight, requiring no scrubbing and removing stubborn black spots effectively.

Summary

Using white vinegar left on black stained silicone sealants overnight offers a no-scrub, easy way to remove mould, protecting bathroom and kitchen surfaces from damage and odor.
