Removing tape residue- do's don'ts & maybe's
There are two main types of adhesive used for sticky tape:1. The first, is used for "cellotape", "majic tape" stick-on vinyl lettering and stick-on stripes uses a glycol ether as the solvent for the adhesive that is very slow to evaporate (keeping it "sticky').As you know (if you have every used an old roll of tape) the stickeness does eventually harden- that is why removing old stick-on tape and its residue is so hard. I use ISLAND GIRL cleaners (CKEAR os most potent) to remove this type of residue since it does contain glycol ether and removes even old dried on residue without evaporating away. This is safe for gelcoat and removing stick-on rubber seals but NOT for single -part paint and varnish. You could even remove tape residue from polystyrene with these products.2. The other type of adhesive is white (duct tape, band-aids etc) and never seems to dry out. Island girl cleaners work BUT NOT ANY BETTER THAT WD-40. On gelcoat, you can also use xylene-based solvents such as Goof-off (and probably gumout carb cleaner- if does not contain more unselective solvents (EPA requres statement on bottle for toxic solvents) Now some caveats:a_BE VERY CAREFUL WITH ANY SOLENTS on partially crazed plexiglass (o rheat-bent plexigass) - can "craze" some more. b) be careful with citrus cleaners- when concentrated they can dissolve vinyl and polystyrene, rubber etc.c) DO NOT USE ACETONE (or high acetone content solvents such as lacquer thinner) This is a non-selective solvent that will dissolve most plastics such as gelcoat, vinyl, paint (even many two-parts), and will cloud up plexiglass. THere are possible exceptions when used very quickly and carefully- but if in doubt avoid their use.Sorry to be going on but I have publicly cleaning things and comparing products for nearly six years!Jim Willis
