The worst thing for a bathroom mouldy silicone around the shower and tiles. When the silicone is black with mould you may be able to get heavy duty cleaner to remove it all. Having said that if the problem is that bad it might be easier and better to remove it all and start again.

A professional bathroom fitter is always the best option to do the job properly and you will find a few local to you on TRADESCOPE.

Before you start always look at your work area and make sure that it`s squeaky clean The main reason for this is before you reseal make sure that you have removed any limescale and vinegar is the best way of doing this so finish off cleaning the area with a cloth soaked in vinegar and leave for half an hour. If the vinegar has damaged or dulled the surface, you may have to think about other options.

Once you have removed all of the limescale you can then get on to removing the silicone with your scraper. Once you`ve got it all off you are ready to give it a final clean down and then apply the silicone.
