Marketing consultant Beth, of Brighton, posted before and after snaps on Facebook and it went viral getting over 5,000 likes, comments and shares.
She said: “I decided to give it a go.“
It took around five minutes to cover them inside and out, then I left for 30 minutes in the bath.
“Then it was another five minutes or so scrubbing with a toothbrush, then a cold water rinse in the bath and 24 hours left to dry in the garden.”
She added: “I didn’t think it would actually work.
“It wasn’t like they were going white in front of me.
“The rubber soles did when brushed.
“But they only really showed up when they had dried.”
Beth continued: “I did it due to the cost of living crisis for me personally and to help other people struggling.
“New Converse are over £40 and the shaving foam was £1.
“I have loads of slightly battered trainers in my wardrobe, so I’m now going to work on and save myself forking out on new pairs.
She said she was blown away by her post going viral.
“I was shocked. It’s still going as well.
“There’s a fair few people who are saying it’s a new pair of trainers, which is definitely isn’t.”
In her Facebook post, Beth said: “So the shaving foam thing definitely works.
“It was just Gillette. I left for about 30 minutes then rubbed in with a toothbrush.
“They look gross. I broke down on the M25 and they got muddy.
“Then I put them in storage so there were actual mould spores on there.
“The foam got rid of all of it. I washed the laces separately in the washing machine.”
Katie Fairclough said: “Wow. I might try it on my Vans, they have gone yellow.”
Danielle Irving added: “Oh my God, that’s actually amazing.
“I can’t believe it, they look so fresh now.”
