Yup! I do it! PVC cement a cap on the bottom and leave the top loose of course! Works great!
Don't yada yada the warnings about properly disposing of those rags...they will combust if you are not careful....buy an empty 1 gallon paint can and lid at Home Depot and put them in there with a little water and close the lid tight.....keep em wet and throw them out when the can fills up!
