That’s rather wasteful.

Echoing the previous two, definitely check and change your air filter! If you have very furry pets/smoke/live in an older home/etc, filters have to be changed sooner than the standard three months (1.5 months) and use one with a higher MPR grade. Ask your landlord to have the air ducts cleaned- this makes a huge difference and isn’t super expensive with a discount (Groupon and HVAC Co sites!). Are you running your bathroom exhaust fan regularly? Vacuuming the vent is a good idea (try to hit it every other month or so), but if it’s older and/or hasn’t been cleaned in a minute, you should take off the vent to give it a good cleaning…I warn you from my own recent experience, the potential ick factor underneath that vent is up there with the inside of a kitchen sink drain… I’m not exaggerating- I wasn’t prepared and cried when I popped off that plastic exhaust vent. Anyway, hope you find a solution- dust is the bane of my existence I feel your pain!

For those who don’t want to risk any unintended damage or discoloration to either curtain or towel, you can also hand wash curtains and liners using baking soda on a microfiber cloth (I read this on a professional maid service site, so I’d say this is pretty reliable). Just rinse it with warm water when you’re done, which is very easy to do if you have a handheld shower. 🙂

I just found out on another site that you need to use hot water when killing off the mold and mildew. Over 140 degrees in your washer machine.To kill mold/mildew (which are living organisms) on white cotton t-shirts, wash in HOT water.

Cold water prevents it from shrinking for your curtain (by itself). I always wash my curtains with Woolite. The plastic Liner & tub mat, 2-3 light colored towels are washed together in the recipe above. I hope this helps you Sue V.
