I bought a generic silicone face cover on amazon and I like it. You can easily wipe it down between uses or take it off and wash it properly.
This is the one I bought but I'm sure the others are fine too: https://www.amazon.com/Topcovos-Interfacial-Sweatproof-Lightproof-Anti-Leakage/dp/B08MQM31CQ/
I got this one and I'm quite pleased with it:
Topcovos Newest VR Silicone Interfacial Cover for Oculus Quest 2 Face Protect Skin Sweatproof Lightproof Anti-Leakage https://smile.amazon.com/dp/B08MQM31CQ/ref=cm_sw_r_apan_glt_i_2F18ETYYNASGXJ2ASSYT?_encoding=UTF8&psc=1
It's cheap and it gets the job done. I love it.
To add: And is not as good as third party covers that are almost identical but include flaps that go either side of your nose and block out light.
Amazon had a prime eligible one that was ok. The nose area didn’t fit but the silicone was softer than my aliexpress one and smoother.
It’s the one by topcovos. https://www.amazon.com/gp/product/B08MQM31CQ/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 I see that it doesn’t offer 2 day shipping now though so maybe they got sold out.
Someone told me to get this
It was worth it. It's easy to clean, comfortable and it blocks light.

Would highly recommend one of these for future use
I know it shouldn't be necessary, but I purchased this and am very happy with it. It hugs your face in a good way to prevent sliding and doesnt absorb sweat. Plus it stays cool so every time I put it on it reminds me of the "cool side" of a pillow.
