Thank you for your inquiry, Leonard! The aerator can be removed and cleaned/soaked in a 50/50 (vinegar/water) solution. There is no aerator wrench designed for the Delta Transitional Beverage 1977-BL-DST faucet. There aerator of this faucet simply unscrews from the end of the spout. If you are unable to unscrew it by hand, then we would suggest using a 50/50 or stronger mixture of tap water and white vinegar. Soak a rag in the mixture and wrap the rag around the aerator area. Use tongs if necessary. Leave the rag in place for 15 minutes or so. This should help dissolve the calcium and lime build up, so that the aerator will unscrew for you. Remove the rag and attempt to unscrew the aerator. Repeat if necessary up to 4 times, taking care to protect surfaces that may be damaged by vinegar. The white vinegar can stain porous stones like granite, limestone and marble. We also do not recommend using pliers or channel locks on the aerator as the tools can damage the exterior finish on the aerator.
