If US and other ally nation ships that specialize in mine detection and removal had free access to the strait, how likely are they to be able to clean it out?

Thank you for such an exceptional offer.

What is the difficulty level to detect and sweep for these mines? Is it cost effective to have to do so constantly? Are anti sweeping countermeasures available and cost effective for Iran?

What else would be relevant to ask in this context I may not know to ask but you’d consider sharing that might be useful context?
