Melba. You over react. You over clean. Fungus on skin is not a deadly disease, so why the drama? Put some daktarin on skin. Wash things normally. Cleaning carpets so heavily can actually make pollution in house worse as you degrade the fibres and the glues. Give drops to cat.

talk to your doctor and do what they say

This reminds me of a friend I had. I made her high quality face masks with special medical filter I bought overseas. I showed her how to wash them , telling her they were delicate .

Then later she told me she scrubbed and wringed them hard to clean them well. I told her she ruined them and made them useless by ripping up all the filter in the inside layer and removing the special chemical that repelled germs.

She just did not want to believe me that scrubbing was wrong. I gave her no more masks, they took a long time to make and were expensive.

Good enough is good enough
