Dry Cleaning Soot Eraser Sponge - (4-Pack) for Smoke, Soot, Dust and Dirt Removal

Product Information

In the Arbocel ® cleaned sample, the dirt has mainly been evenly removed. Between the fibres, there are some traces of dirt and small deposits that, due to their appearance, seem to be traces of the canvas priming. This is also confirmed in the spectra. Fibres remain twisted and there is no significant movement. The dry-cleaning technique with the best results is microblasting with powdered cellulose, as canvas is free of residues of particles, both from the cleaning material and from the dirt.

The increase in L* (D65) can be explained by the removal of dirt, dark in tone, resulting, therefore, after cleaning, in spots of greater luminosity. However, considering that the tone of the materials used for cleaning is lighter than the old canvas (yellowish due to the oxidation of cellulose) an increase in L* (D65) could also come from the particles of residues of the cleaning materials. It seems reasonable to suppose that this is the case, at least in part, of spots treated with Milan® and Akapad ®Soft sponge, where a high presence of cleaning residue particles and a lower degree of cleaning were observed in optical microscopy and SEM–EDX analysis.

Apply your chosen paint to a small section and assess stain visibility. If you can still see the stains, apply another coat of primer to the entire wall. Once you’re happy with the coverage, use a paintbrush to coat the wall evenly. Leave to dry for around two hours before moving on to the second coat.López A, Narváez J, Tello N, Blanc R, Espejo T.

Lastly, the sample cleaned with Art Sponge ® has a less modified appearance. The spectra indicate traces of dirt particles and highlight the presence of Ca, a characteristic chemical element observed in the microanalysis of the smoke sponge (see Tables 4 and 6). Old canvas samples

In: XVII international meeting on heritage conservation, Castelló. 2008. Compared with the soiled surface, Sq of Milan, Akapad ® and Art Sponge ® are only slightly higher (± 1 μm) and Sa (± 2.5 μm). The highest increase in total height corresponds to Arbocel ® (Sa ± 4 μm; Sq ± 3 μm) indicating that cleaning is more effective because more soiling is removed (as can be seen in 3D images). Sz, a parameter related to the absolute values of Sp and Sv, presents similar behaviour but in this case the Akapad ® value is higher, thus indicating a significant lifting of some fibres, as can be seen in confocal images.

Akapad white has been developed for the gentle cleaning of papers, plans, posters, legal documents, plus many more very sensitive surfaces. Akapad white has shown particularly positive results with regards to ageing resistance in the cleaning of paper.

It is possible to paint over smoke-damaged walls. However, you shouldn’t apply paint straight over smoke stains, as doing so won’t cover them up. Start by removing stains with a dry cleaning sponge, followed by a wet cleaning method. Then, apply a durable primer to the walls to prevent the stains from showing through.
