I hate when my clay pots start forming salt deposits, as they can be really hard to remove. Well I found a simple way in which you can remove them without a ton of work.
Get yourself an empty spray bottle. Combine equal parts of white vinegar and rubbing alcohol. Spray this mixture on your clay pots that are forming the salt deposits. Use a scrub brush to loosen the salt deposits. They should start breaking down a lot easier now. If not apply a bit more of the spray solution and scrub again.
Once the clay pots are clean allow them to dry before you plant anything in them. That is a simple way of cleaning off those tough salt deposits.
