Gtechniq Marine Water Spot Remover is intended for targeted removal of salt/fresh-water spots and mineral deposits. Mariners Warehouse SKU 108784, manufacturer code MWR 0.5, supplies one 500 mL MWR container.
The MWR marine product is explicitly ready to use. The source’s descriptive concentrated wording does not create a dilution instruction. It is a mineral-spot cleaner rather than a compound, coating or general deck wash. Manufacturer examples include gelcoat, fiberglass, glass, chrome and metal on permitted matte/gloss finishes. Check the actual coating, finish and label restrictions. No universal approval or repair of permanent etching is implied.
The listed purchase supplies one 500 mL MWR container. 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.
Shake well, spray onto the permitted water spots and buff with a suitable clean microfiber cloth before the cleaner dries. Repeat as needed under the actual label. No numeric dwell or dilution is supplied, and the separate Gtechniq deck cleaner’s 3–5-minute rinse method does not apply to MWR. Use the finish-maker’s requirements alongside the product directions.
