Removing stubborn mould

[Sunshine288]

Anyone got any tips on removing stubborn mould stains from tiles? We have a shower room downstairs and it’s driving me mad!
Last week I tried Kilrock mould remover brush on gel, then today I’ve jet washed and have just used Dettol mould and mildew cleaner.
All have helped and I can see a massive difference but there are still some stubborn black stains remaining!

Anything else I can try please?

HG Mould spray. You can buy it in Tesco or Amazon. It’s about £7 and open all the windows when you use it as it stinks but it really works.

I actually saw this when I was in B&Q the other day and nearly got some! Thank you will give it a try
