Yous can usually practise this with h2o, vinegar, chemicals, or heat, depending on the type of caulk.

   • Commercial caulk remover is the simplest choice and may exist your all-time option for silicone caulk. Apply the caulk remover past squeezing a wide bead along the caulk line, completely covering it from terminate to end. Let information technology sit down for several hours every bit directed on the characterization.^[i]
   • If y'all are dealing with non-acrylic water-based caulk, yous tin soak the caulk with saturated rags for 72 hours to soften the caulk effectively.
   • If dealing with h2o-based acrylic caulks or polyvinyl acetate resins, soak the caulk by dampening it with iso-propyl rubbing booze.^[2]
   • To use heat on whatsoever class of caulk, utilise heat from a hair dryer on the everyman setting for 30 to 40 seconds. Work in patches of about 8 inches (20 cm) at a fourth dimension.^[3]

2. 2

   Slice through the caulk with a blade. Use a small razor bract to cut through each end dewdrop of caulk, exposing the edge of the line.
