IT'S NO secret that damp can cause loads of damage in your home.
But one place you might forget to look is on your windowsill, especially under any pots where marks might go unnoticed.
Fans of cleaning sensation Mrs Hinch recently shared some of their top tips to banish the grim marks on Facebook and they're loads easier than you might think.
When one keen cleaner tidied her daughter's bedroom she noticed a strange mark that was left on the windowsill.
She explained: "Just moved one of my daughters lights off her windowsill and looks like it has got wet from the condensation and left a rust mark any suggestions to removing it?"

But after already trying to remove the messy mark with bleach and Hinch's favourite The Pink Stuff, the mum was all out of ideas.
Luckily, fellow cleaning fans had a few suggestions.
One of the main recommendations was to use CIF cream cleaner to get rid of the mess.
But other users suggested using WD-40 instead, with some even swearing by it.
One person explained: "I had marks on my windowsill and like you I had tried everything.
"Eventually squirted WD-40 after seeing a hack on YouTube and it worked using wire wool (I had the wire washing up thingy) but it got all the marks out."
All you need to do is spray the WD-40 onto the rust mark and after around 10 minutes you should be able to wipe it away.
If the mark is more on the stubborn side, try scrubbing it with a toothbrush to get rid of it.
Other cleaners suggested giving The Pink Stuff another go, but this time with an abrasive sponge.
"Pink stuff paste keep rubbing it will come off," one person wrote.

Someone else suggesting opting for a microfibre cloth instead of a sponge for the best results.
They said: "Pink stuff paste using a microfibre cloth it works I had same problem."
Meanwhile, some cleaning fans thought a bit of hand sanitiser would easily remove the marks without much scrubbing.
"Soak in hand sanitiser and then wipe clean," one person commented.
