The importance of cleaning auto glass

La auto glass cleaning is one of the most important but often underestimated operations in vehicle maintenance. Interior windows tend to get dirty quickly from vapors, dust, fingerprints and smoke residue, creating a film that impairs visibility.

Regular cleaning prevents fogging and the buildup of halos, especially when using air conditioning or heating.

The best cloths on the market include Glass Ultimate Microfiber Cloth, with a unique, finely woven texture, captures the tiniest particles of dirt, ensuring thorough cleaning and a crystal-clear result. It is extremely absorbent, easy to handle and allows you to distinguish the cleaning side from the finishing side due to its light color. It is designed to go over all smooth surfaces with extreme comfort, adapting perfectly to the treated surface.

Remember: MA-FRA cleaners never contain ammonia, so they respect the surfaces of the materials they come in contact with.

. Always match two cloths: one for cleaning and one for drying and finishing .

As for the cloth technique: fold it into four. That way you get eight sides to use, each clean. Start at the top and work your way down, without going over areas already treated with the dirty side.

Car window cleaning in summer and winter: how to adapt the method

Summer - insects, dust, smog

Summer brings with it long days, travel and ... lots of bugs that go to impact the windows. Hot asphalt also raises a lot of smog and fine dust that sticks everywhere.

Use Mafra's Killer for insect removal, the product is suitable for removing insects from bodywork, windows and glass, bumpers and headlight glass. It dissolves any insect residue, even dry ones in a few moments.

After gnat removal apply Glass Cleaner perfect for quick and deep cleaning of windows, even when on the road. Always keep one in your car, Glass Cleaner is also available in 150ml size with a microfiber cloth.

• Glass Clean & Shine to protect exterior glass with an anti-halo veil.
• For interior condensation, on the other hand, choose Wipes Clean, a pack of 20 disposable wipes created to give windows brilliant transparency, cleanliness and protection.
