Birthday I got from my sister the ALCLEAR Ultra-Microfibre window cloth paid. Something great, I've never had in his hand! It keeps really delivers what it promises: Impeccable, streak-free windows! Just great !!! I have now introduced it in my Arbeutsstelle, because there we have at least a dozen large glass doors. No problem - we brush with "the left" - No, the Super Fenstertuch of ALCLEAR !!! I would like to give 7 stars!
