Silicone and grout replacement and cleaning
It is recommended that every 12-24 months the silicone in your wet areas is replaced by a licensed builder. Silicone has a relatively short life span and can crack and peel, if this happens it becomes an ineffective barrier, and can lead to water damage.
If your shower is wet for longer then 48 hours, this is ideal for mould spores to proliferate and mould growth to occur. Once this happens, mould cannot be ‘cleaned’ from silicone – it must be replaced! Grout, on the other hand, can be cleaned if you notice minimal mould growth by simply scrubbing it with equal parts bicarb soda and a non-citrus based dishwashing liquid.
