RV antifreeze recalled for risk of methanol poisoning

Many RVers winterize their vehicles with an antifreeze designed for RVs. When spring arrives, they flush their systems and all is well. If that’s you, here’s a warning that if ignored could, worst case, cause blindness or death. So pay attention.

The recall involves Shop Pro RV & Marine Antifreeze products manufactured by Prestone for AutoZone. Only bottles filled with blue fluid in one-gallon, clear bottles with date code FT21281 on the bottom of the bottle below the back label are included in the recall. “Shop Pro RV & Marine Antifreeze” is printed on the front of the bottles. If your bottle is filled with pink liquid, it is properly labeled, and can be used.

These improperly filled bottles do not have the mandatory cautionary label for products containing methanol, including that the vapors are harmful and the product can be fatal or cause blindness if swallowed. Also, the directions on the bottle for properly flushing a potable water system can fail to adequately remove the methanol, presenting a risk of ingestion. Products containing methanol pose a poisoning hazard through inhalation or if ingested.

If you used this product to winterize your RV, immediately stop using it and contact Prestone for a full refund and instructions on how to properly dispose of the product. Consumers who have already used the mislabeled product in any potable water system SHOULD NOT DRINK WATER FROM THE SYSTEM and immediately contact Prestone Products at 866-625-5322, Monday through Friday from 8 a.m. to 5 p.m. CT, or online at or and click on Safety Notice at the bottom of the page.
