Welcome, my name is XXXXX XXXXX I will do my best to help you with your issue.Common household bleach is the most effective product for killing mold. But you need to make sure the surfaces dry out to prevent mold from coming back
Ok what is the best way to apply the bleach?
also since the corner of my carpet was wet and probably moldy, should I treat the carpet and pad, or it is better to just get rid of that part of the carpet?
A sponge. Be sure to wear gloves and a high quality mask. You need to get things dried out but If you can't them removing the items is also an option
The bleach may discolor the carpet
Ok -- it is not good to put a fan on it though right? Or maybe after the bleach is applied and the mold is killed?
Best to kill the mold first. If it permeates the pad and/or carpet probably best to get rid of them then let it air dry.
No fans with mold present
Is it ok to spray bleach with a bottle?
Yes you can use a spray bottle too. A 50/50 mix with bleach and water should do the job
ok and if with a sponge then use 100% bleach?
No same 50/50 mix
ok thank you
