Question: I once put a dirty shopping bag on the sink table, this bag may be contaminated with blood since i saw some brown stain on it. I used a rag to clean the table surface after discarding the bag and washed it after finishing very briefly. There is no obvious stain left on rag. I keep on using the rag in the wash room for drying the sink table a couple of days after that. Since it is beside the tap, the rag is almost always wet.
1. My question is that if the stain on bag is HIV contaminated blood would HIV survive in rag and further contaminated my sink table when I used it? Will I catch HIV if I pick my pimple to be a little bit bleed after touching the sink table and rag without washing hands again?

2. And later I finally realized it may not be very clean and put my rag outside for 2 days under the sun. In this case, will virus all dead?
Thanks

How about case 1. It has been several hours though

I am not sure whether the stain on the bag is dry. But is not very wet like dripping though

If there is blood stain but not dry enough. Also no risk in the above scenario I mentioned?
