I never tried freezing them, I'll try that next time, but I do always wrap up rollers and brushes ( sometimes the whole tray too) and put them in the fridge overnight so they are ready for the next coat or rest of the job. Never had a problem even if I missed a day and they sat 2 days. Then when you wash that brush and roller cover, use warm water and a little shampoo, and rinse a few times, comb the brush with an old comb then let them dry with the nap or bristles not touching anything. I always keep lots of rags around when painting, a few wet and most dry, anything absorbent will do, though I prefer cut up old bath towels to anything I have ever found sold as disposable rags. The "box of rags"..really heavy duty paper towels actually, that they sell at Home Depot etc will work OK in a pinch though, the most important thing is to have plenty of them.
