As salamu alaikum,

This is quite an important question - can we dry clean our clothes? I think there are a couple of issues here that I hope you can answer dear Mufti:

1. Is the usage of (alcolhoic) solvent in itself OK?
2. In a dry cleaning machine, the same solvent is used to clean a batch of clothes, which may have najasa - so since the solvent is isn't refreshed, can the clothes become clean? ...But bear in mind that the solvent is different from water - it takes off stains etc from clothes, but the solvent itself (with all dissovled stains) is removed from clothes anyway...so even if the same solent is used to clean many batches of clothes, it takes up all najasa but doesn't infect the clothes...i think but am not 100% sure of the technology.
Allah Knows Best!
Jazakallah khairun!
