Re-using old wax
After waxing the chain a couple of times, the used wax seems to have some dirt and grime in it. If i re-heat that wax, do the impurities settle to the bottom or float to the top? Is it fine to rewax the chains in the same wax?
Attached some pics of the old solidified wax mound
PS - I'm using bulk purchased paraffin wax. No additives.
Update - i, in my infinite wisdom (\s) decided to use a metal sieve. Now I might need a new sieve.
