Has anyone ever had a soap puck dissolve on them? I submerged my VDH puck in hot tap water, went into the bedroom to get the rest of my supplies, I came back and the puck was nearly gone. I'm thinking the temperature of the water was too high (even for bathroom). Thankfully it was only a puck of VDH and nothing more expensive, I can replenish it tomorrow with one from Wally World for less than $2, but it was the point of the whole thing that shocked me. I did not have my brush moistening up in that water, thankfully.
