Mold and mildew are often lumped together because most everyone associates mold and mildew with rot. However, mold and mildew are structurally different, and they need to be removed in very different ways. Unless you are allergic to mildew, it is the easier of the two substances to remove. Here are three reasons why it is easier to remove.
Mildew Dies When There Is No Heat AND Moisture Available
Undoubtedly, you have seen the mildew on your shower curtain and understand that mildew collects where it is wet. However, mildew cannot stay where it is wet unless it is also hot and humid. If you expose mildew to cold, dry air, it dies, and then you can just wipe it away. A "cryo-can" of concentrated cold air emitted from a spray can-like container can help, Just be sure to wait for the cryo-substance to dissipate before wiping away the dead mildew fungi.
Mildew Is More Easily Killed with Bleach
While you can use bleach on mold, you may cause its spores to separate and float away while you are treating the area with bleach. Mildew, on the other hand, requires moisture to stay, and it is tricked into thinking it is exposed to more moisture when in fact it is being dissolved by the bleach. Mildew also does not spread in the same ways as mold, and that helps you to drop a mildew-covered item into a tub or bucket of bleach solution and kill it all before it can spread.
If You Kill All the Mildew, It Does Not Return for a Very Long Time
Let's say that your shower curtain has quite the collection of yellow and black mildew along the bottom edge. Now, if you submerse that in a bucket or tub of bleach, the mildew dies and it cannot return without new mildew fungi developing and clinging to the shower curtain. However, that is tricky to do, since the curtain will have been scrubbed of mildew and there is not much for a single mildew fungus to cling to.
Mold, on the other hand, will pop out its baby spores and send them off to stick to whatever they can. When that happens, the mold is renewed and spreads to the area where it originated. Then it looks as though you never removed the mold. If you get the help of a good mold and mildew remediation specialist from the start, you will not be repeating these scrubbings again in the near future (or even in the distant future, as is the case with mildew).
