Floors:
Steam Mop- We have tried every mop solution & even tried using simple green on our floors. Nothing completely cleaned the lotions off the floor & it was slippery & dangerous. We've found that a steam mop helps melt the lotions, making it easier for the mop to get them up. I like that it doesn't leave a chemical residue. It also sanitizes. No more mop solution to buy either!
Clothing/linens:
Washing Machine- I highly suggest a front load washer that has a sanitize feature. The sanitize feature heats the water to melt lotions & kill germs.
Soaps- We all need a free & clear detergent, not just Ethan. We've found that Costco's Kirkland HE Free & Clear works very well. If we get puralube eye ointment on clothing, using simple green or dawn may get rid of the stain (nothing else works).
Bath toys:
Since many kids with ich spend a great deal of time in the tub, you might have lots of tub toys too. We place bath toys in a bleach solution at least once a week. Pay careful attention to toys that can hold water (especially squirter type toys).
