I have a steam cleaner, I have a mouldy shower. Lets combine them!

Has anyone got any experience of this? What should I look out for or do for preparation? Clean the mould with bleach first? Should I avoid steaming anything? Just go for it and report back here? 

Or is this a bad idea and I just need to use ajax and elbow grease?

What do you think caused the mould?

Steam cleaner will remove mould to an extent. But what's mouldy .... Walls/grout or silicone. Each requires a different method to eradicate. Ignore anyone that says vinegar is the solution to any of these situations.

Then address the ventilation issue

After every shower you must wipe down the shower glass and tiles then dry completely with another cloth.  Every single time.

Grout and silicone. I'm expecting to replace the silicone. 

There's an extract fan in the bathroom, it is used. But I think the shower door getting closed reduces it effectivity (after the shower).

Lazy family not using the supplied shower squeegee to remove the water from the shower.

Oh I know! Best of luck getting Mrs 10 to do it though!

Yeah I don't do those things either but I also don't have a mould issue. 

Correct ventilation is key.. most bathroom extractors are grossly undersized/inefficient Removing the damp air due to poor ducting.

Mix a paste of thick bleach and bicarbonate of soda. Brush it on to the mouldy grouting and silicon, leave for a couple of hours or overnight. Wash off and repeat until your happy it's clean enough. Top Mumsnet tip.

If it's really minging then it'll need re doing, but the bicarb trick is very effective and excellent for periodic cleaning

Agreed. Or, put another way, more ventilation than you can throw at it. Personally I always open the window and the door and have the light/extractor on, even in winter. I've had snow blowing in the window before now, although I admit that was a little extreme. And then wipe down with cloths, squeegee, Karcher window vac etc afterwards. Point is, after 15 years,there's basically not a spot of mould on the grout, although the silicon was replaced a couple of years ago. So once you've fixed it, keep it fixed with good ventilation.

Silicon- I was sceptical when Facebook suggested this, but it worked a treat: Squirt bleach along all the silicon sealant, then press toilet tissue on to it and leave overnight. Remove and rinse, absolutely no mould remains! I was gobsmacked how easy it was.

I was going to come and say use bleach because it does work , covering with bog paper is a bit pointless Imo.

 

Also use it too much or too long and it will yellow sealant 

 

Alternatively use cilit bang mould remover which appears to work faster

 

We never wipe down the shower but we do leave a window open after so it all dries

I'd watch the bleach in the shower as it can cause knock out gas, I once ended up with a week of coughing but hopefully no long-term damage but Google it and it's not good for you

Just round the rim and close the lid n open the windy

HG Mould Spray.

Use it all over the shower every couple of weeks.... Keep the windows open when you spray it. 

Makes "bleach" seen like water in comparison. 

It won't kill the mould - nothing will - but I guarantee you won't see it any more.

HG Mould Spray* +3

*Someone recommended Astonish Mould & Mildew Blaster as being as good, it is not...

 

If you do redo the silicon, use DOWSIL™ 785 Sanitary Acetoxy Silicone

 'DOWSIL™ 785 Sanitary Acetoxy Silicone'I spent ages digging out and replacing sealant after the shower developed a leak. I must've done it about 2 or 3 times until I discoved this stuff. Works perfectly being high modulus. I also found HG to be the most effective but doesn't lead to a permanent eradication, just need to do it every now and then.

Got to be honest my bath/shower was minging for years. Hit it with a spray bottle 50/50 thick bleach and water, sprayed that bastard down and now it's great. I do the same every now and then when I see bits of it discolouring again, every month or so, and it sorts it right out.

For some reason I opted for clear silicon sealant around where the glass panels are mounted on my bath, I can now see mould under  it and can't get it to shift (have tried bleach and HG mould spray amongst others, isn't the latter just squirty bleach anyway?). It just doesn't penetrate far enough under, might give that soaking toilet paper in bleach and leaving it overnight idea a go though.

Bleach and toilet tissue method works well for me.

Mine's due another go actually.
