Dirt naturally accumulates in the joints between tiles, turning them black and unhygienic. To clean floor joints, we recommend using a non-aggressive alkaline product like FILAPS87 diluted 1:5-1:10 (1 litre of product per 5-10 litres of hot or lukewarm water), using a brush to remove the dirt. Rinse abundantly. For tiled walls, use the handy FUGANET spray detergent. Spray it onto the surface from about 15 cm away, then wipe over with an abrasive sponge and rinse off.
If the joints are heavily soiled, wash with DETERDEK descaler diluted 1:10 (1 litre of product per 10 litres of hot or lukewarm water), using a brush. Rinse abundantly after treatment.
Once the surface is dry and clean, you can protect the joints with FUGAPROOF eco-friendly stain protector.
You can find DETERDEK detergent and FUGAPROOF stain protector in the FILA KIT CERAMICA, a kit of products designed specifically for maintaining ceramic surfaces.
