I have just been away from my house for about 6 weeks to find a return to mould spots on some of the walls and efforvesence salts on much of the floor tile grout. I have installed some air vents and left some windows open to prevent this sort of thing but obviously it did not work.
I intend to get some bleach to wash the mould off the walls but I am not quite sure what I should be looking for in the shop. Google translate is not much use as it just comes up with Spanish words for whitening. Can anyone advise please.
Unfortunately I am not sure what to do about the efforvesence salts on the tile grout in terms of cleaning it off and secondly preventing or delaying its return. The efforvesence is just on the interior tiles and not on the exterior.
All advice gratefully received.
