FELTPEN FADEOUT (FPFO) is designed for the final removal of shadows and traces of inks and dyes and other graffiti markers from all surfaces; porous and non porous.FPFO will also remove some spray can stains / ‘ghosts’ (particularly reds) from delicate and porous surfaces, and is designed to work in conjunction with World’s Best Graffiti Removers.

FPFO can be diluted with water to use as a high foaming cleaner for the removal of organic stains dirt and fats as well as sanitize surfaces killing micro organisms (germs, bacteria, fungi etc.)

Use for the final removal of inks and certain spray can stains on painted and coated surfaces, plastics, concrete, cinder block, terrazzo, stone, marble, granite and most other surfaces.

Comes in 32 oz, 1 gallon containers in both single and case quantities.

Why FeltPen Graffiti Shadow Remover?

  • Unique UV sensitive formulation draws inks and other stains out of surfaces.
  • Can be used while BARE BRICK STONE & MASONRY REMOVER or SENSITIVE SURFACE REMOVER is still on the stain OR after dissolving as much of the graffiti as possible using these removers (choice of remover depends on type of substrate.)
  • Excellent for removing leather dyes and inks that have shown resistance to removers, ‘burnt into’ / stained paintwork or coated surfaces, or wrapped into porous surfaces creating a stain.
  • When diluted, creates a highly active cleaner for use cleaning smoke films, greasy marks, carbon deposits, food spills, mold, fungi, and other soilage.
  • Biodegradable


Coverage Guidelines

Exact coverage varies depending on type of stain and the number of applications needed.

  • For stain removal, use FELTPEN FADEOUT neat.
  • On painted/coated surfaces expected removal is approx. 1000 sq ft per gallon.
  • On porous surfaces requiring more coats, expected removal is up to 300 sq ft per gallon

For hot weather removals avoid direct sunlight whenever possible. Wet surface down first and apply FPFO to damp surface. Allow for longer dwell times in cold weather. Expect considerably slower reaction times in weather below 50° F / 10°C. May need to cover and leave on longer overnight.

FELTPEN FADEOUT is a concentrated blend of surfactants, foaming agents, alkaline salts, and sodium hypochlorite designed to draw inks, pigments and dye stains out of surfaces. When diluted with water it acts as a powerful cleaning agent and will attack and bleach all
types of soilage.

Product Use Instructions 

Use for the final removal of inks and certain spray can stains on painted and coated surfaces, plastics, concrete, cinder block, terrazzo, stone, marble, granite and most other surfaces. Do not use for cleaning aluminum or alkali-sensitive surfaces such as polished floors

Removing Ink and Dye Stains:

After removing as much of any graffiti marker as possible, pour a small quantity of FELTPEN FADEOUT (FPFO) into a small bucket and then apply as thickly as possible to the remaining shadows with a nylon brush. When shadows have disappeared, wipe clean with a damp toweling cloth.

On all smooth or porous surfaces including signage, plastics, stone, concrete, granite or marble, you must attempt to remove as much of the graffiti as possible by first applying SENSITIVE SURFACE REMOVER (SSR), in the case of marking pens, or BARE BRICK, STONE AND MASONRY REMOVER (BBSM) in the case of spray can paints.

The time taken to work completely will vary from instantly, to several minutes, to even overnight in some cases.On inks or dyes splashed or thrown onto concrete, brick or porous surfaces etc., it may be necessary to leave FPFO on overnight. When doing this, we suggest applying FPFO as thickly as possible and covering with black plastic. You can tape the plastic to the wall along the three bottom sides first, and then brush on as much FPFO as possible before sealing the top of the bag onto the wall. This will keep the product wetter for longer, as well as prevent anyone from rubbing up against the wall on the affected area.

Occasionally, some markers or spray can paint shadows may not appear to have been affected by FPFO. However, wiping off with a damp cloth in the case of smooth surfaces or pressure cleaning in the case of brick, stone or masonry surfaces can achieve quite surprising results. Do not be concerned if you need to apply this product more than once.

Removing Spray Can Stains:

FELTPEN FADEOUT is extremely beneficial in removing certain spray can stains on porous masonry and concrete. After dissolving as much graffiti as possible with BBSM, an application of FPFO during or after the final rinse will eliminate any remaining pigment or stain in the surface.

This method (which is illustrated in the sequence below) can be used on a variety of spray can colors, however it is especially useful on RED spray cans and ANY color containing red, ie: oranges, pinks, purples and browns. These colors all contain fine red oxide pigments and are the most likely to leave a residual stain. The stain can be easily removed with a generous application of FPFO.

Once FPFO is applied thickly to the stain, the fading process normally takes only a few minutes to less than half an hour, but longer dwell times may be necessary. Fortunately, once you begin to see the stain disappear (even marginally) you can fade the rest, so be patient and reapply FPFO if needed.

FELTPEN FADEOUT (FPFO) can be used as a high foaming cleaning concentrate with bleaching action when diluted with water.

Dilute with water as follows:

Light soilage 1:100
Regular cleaning 1:20-50
Mold removal: 1:20
Heavy soilage: 1:10

1. Make up desired diluted solution of FPFO.
2. Wash the surface with solution.
3. If surface is rough, scrub the solution in with a nylon brush, try to reach into crevices.
4. Rinse with clean water. Dry or leave it out to dry. To remove oil or grease spots, scuff marks and hard to shift spills, use FELTPEN FADEOUT neat.


TIP 1. On painted walls FELTPEN FADEOUT can be applied first to thick feltpen markers without agitating with the brush. Immediately after this, apply SENSITIVE SURFACE REMOVER in the normal manner. The FELTPEN FADEOUT will absorb the dissolved staining inks thus avoiding ghosting.

TIP 2. Any spray can graffiti that changes color when BARE BRICK, STONE AND MASONRY REMOVER is applied, will also be affected by FELTPEN FADEOUT.  Many shadows will disappear if FELTPEN FADEOUT is applied during and after BARE BRICK, STONE AND MASONRY GRAFFITI REMOVER application. Remember to look out for subtle changes in colors such as greens turning grayish yellow and reds turning crimson. The effect of this technique can appear to be magic, leaving onlookers totally gobsmacked!

TIP 3. Boot polish markers (recognized by thin drips running down vertically from the ‘tag’) and some posca pens (recognized as chalky–style water based marking pens) are best removed with FELTPEN FADEOUT. Wet the tag first with water, leave for a minute or two, then apply FELTPEN FADEOUT. Either wipe, or pressure wash off depending on the surface type.

FELTPEN FADEOUT is corrosive to skin and may produce severe burns if in contact with skin for extended periods. Wear protective gloves, clothing and safety glasses as shown in SDS.

1. Always wear alkali protective gloves, goggles and long sleeve clothing.
2. Always know where water is available in case of a splash.
3. Avoid splashing FELTPEN FADEOUT on clothing as it will bleach / burn holes in cotton and other fabrics.
