Exact code M4716
16 oz • low-drip liquid cleaner
Product-specific label and compatibility checks
Meguiar’s M47 Marine/RV Hard Water Spot Remover is intended for targeted cleaning of mineral deposits and hard-water spots. Mariners Warehouse SKU 55977, manufacturer code M4716, supplies one 16 oz low-drip liquid cleaner.
M4716 is a purpose-specific hard-water spot remover with a thick, low-drip format. It is a different care task from cleaning oily grime or correcting oxidation with a compound. Fiberglass and gelcoat are the core marine application examples. Confirm your exact finish and the delivered label before treating metal, painted parts, clear plastic or other adjacent materials. Broad marine-surface wording is not a universal material approval.
The listed purchase supplies one 16 oz low-drip liquid cleaner. Separate accessories, treatment chemicals, applicators and larger package variants are not confirmed included. Match the exact care task and package before comparing related products or planning your order.
Manufacturer guidance says to spray onto a permitted surface, allow 10–20 seconds for penetration and wipe with a suitable clean microfiber or cotton terry towel. Follow the delivered label for preparation, conditions, removal and any repeat treatment. Do not substitute a generic acid-cleaner soak, abrasive compounding method or an invented dilution. Persistent etching may need a different diagnosis rather than repeated chemical treatment.
