Rust: oxalic acid is the most effective agent but also tartaric or citric acid dissolves rust stains.
SAUCE: Rub the stain with Ocean Floating base wash or Ocean Grovrent before washing. At the strong color of the sauce, such as tomato sauce or ketchup, Ocean Oxi stain sprays need to be used to bleach the stain. Try color authenticity in an inconspicuous place.
SHOE POLISH: Rub with Ocean Floating base wash or Ocean Grovrent before washing to such a high temperature that the material can withstand. If the stain remains, it can be treated with Ocean Oxi stain spray.
